It al depends on what sound you prefer/want to achieve. Acrylic shells sound different than wood but it is not a worse or better sound than wood shells. It is just a different sound; just like different kinds of woods - maple, birch, bubbinga, etc.- affect the fundamental pitch of a drum. And that is just one aspect of the "drum sound." Another aspect are the drumheads: the type of heads you put on them - single/double ply, coated/clear, hydraulic, etc; and how you tune them determines the resonance, attack, and feel of how the drum is going to sound. And another aspect is what sound do "you" want to achieve. That being said, acrylic shell by nature are going to sound boomier and "boingier" than wood shells because the sound does not get absorbed by the acrylic shell like it does inside the wood shell. Wood shells have a more "warm" sound which is a more popular preference. That doesn't mean acrylic sets are not desired. Keep in mind that bands such as Led Zeppelin, Red Hot Chilly Peppers, Mars Volta, Pink Floyd, all have either toured and/or recorded with acrylic sets; so ask yourself what kind of sound do you want to achieve.
I don't own an acrylic set, but I've heard that acrylic shells tend to require just a tad more care than wood shells, especially if you are on the road - otherwise they're brittle and break apart rather easily.
Since you are starting, I would recommend get a wood set. As Tim suggested, you can get a great $500-600 used wood drum set for $200 or less. If your music store doesn't have a used set in your range, try craiglist or ebay. I've seen great intermediate drum sets for as little as $150. As your skills progress and you develop a taste/ear for "your" sound, and once you are ready to upgrade to better/nicer/new set, you be able to make a more educated purchase and get the kind of drumset and hardware you want.
