That's a tricky one. You must consider the question of why B.C. Rich aren't making one anymore.
I don't know how long the run was, but given that the Speedloader is a fairly recent development, it's likely that not very long. I am therefore guessing that the reason it went out of production is that it wasn't very popular.
It's likely that the Speedloader is the primary reason for this, or rather the proprietary string design required. I've just done a quick scan of the Net and I see that things haven't changed much in terms of string availability. Having to jump through hoops in order to restring the thing will probably be a deal-breaker for most.
The fact that a guitar is rare doesn't necessarily mean that you'll be able to get a good price for it. Selling it off now might mean that you'll have to offer a good deal in order to find a buyer. You might be better off holding on to it with the hope of future collector interest.
The other option is getting rid of the Speedloader and installing a standard Floyd. However, it would be a major modification and probably not cost-effective. Plus, such a mod would remove the only differentiating factor, making it just another used NJ Beast.
