IMHO, it's generally not a good idea to buy an acoustic/electric that lists for anything less than $1000. Why? Because no matter how much the guitar costs, some of what you're paying for in an acoustic/electric are the pickups and electronics. In other words, a $500 acoustic guitar is a $500 acoustic guitar, but a $500 acoustic/electric is really a $400 acoustic guitar with $100 or so worth of electronics. At that price point, there's a real difference in quality between a $500 acoustic and a $400 acoustic.
At some price point, the guitars get good enough where the $100 or so dedicated to the electronics doesn't make a huge difference in the quality of the instrument. In other words, a $1000 acoustic guitar is still a $1000 acoustic guitar while a $1000 acoustic/electric might be a $900 acoustic + $100 of electronics. At that price point, though, the difference between a $1000 and a $900 guitar isn't too much---it's not as big a difference as between the $500 and the $400 guitars. Both the $1000 and the $900 guitars are decent quality, and so a $1000 acoustic/electric is probably a pretty good guitar.
So my advice? Buy the best-quality purely acoustic guitar you can afford. If that's around $500, great---there are plenty of decent-quality acoustic guitars at that price. If later you decide that you want to plug it in, that's the time to buy a good acoustic pickup system. That way, you spread out the cost over a longer period of time, and you can always upgrade the pickup later without throwing away the guitar, and vice-versa.
p.s. That Ibanez is pretty, but at $450 including the electronics, there's absolutely no way it's made of solid wood. That's a plywood instrument with quilted maple veneer. Don't get sucked in by its looks. For ~$500, you can get a well-made acoustic guitar with a solid-wood top from your choice of a variety of different builders.
It seems the argument I made above is more controversial than I had expected. Let me try to clarify it a bit.
Suppose you're a guitar maker looking to introduce a new acoustic/electric model to your line. You pick one of your existing acoustic models and decide to add a pickup and electronics to it. The Stew Mac catalog offers a variety of acoustic guitar pickups and electronics systems. The cheapest complete package (acoustic pickup, preamp, endpin jack, wiring) they offer is the L.R. Baggs iBeam Active Pickup System, at $139. Add in the additional labor to install this system in your guitars, plus the markup, and it'll come to a $200 premium. Maybe $150 if you're a huge company and can buy enormous volumes.
So now you have a choice: you can either add $150 to the cost of your guitar, or you can try to find $150 worth of corners to cut from your existing model.
Well, if your existing model is around $1000, it's a lot easier to cut $150 worth of corners and still have a great instrument than it is if your existing model is $450. If you're looking to cut $150 off of a $1000 model, maybe you use A-grade solid wood instead of (prettier but sonically irrelevant) AA-grade. Maybe you stick with a AA-grade solid top, but go with plywood back and sides. Maybe you use cheaper tuners and abandon fancy binding. Either way, you'll cut some corners and still end up with a pretty good guitar. But if you're cutting $150 off of a $450 model, you were already using pretty cheap tuners, and now you're abandoning solid wood entirely and going with plywood throughout.
So now imagine you're the customer, and you're looking at a $450 acoustic/electric. Of that $450, you know that $150 is electronics, so you're really looking at a $300 guitar with a pickup tacked on. The difference in quality between a $300 instrument and a $450 is way way bigger than the difference between a $900 instrument and a $1050 instrument. It's a 50% difference vs. a 15% difference.
I'm emphatically not saying you've got to buy a $1000 guitar to be happy. I'm saying, if you've got $450 to spend on a guitar, buy a purely acoustic one with no electronics at all. Then you know all the money you'll spend has gone into making the best guitar $450 can make. Later, if you decide you simply need to plug it in, you can save up for a great acoustic pickup that you can use to amplify your $450 guitar.
