My crystal ball is still in the shop so there is no way I can predict what the future price might be, but the price sounds reasonable. Its your choice and you could:
a) Wait and see what happens and keep drooling (which doesn't sound like fun)
b) Go out and buy the gun NOW and start enjoying it right away instead of just dreaming about it. (which sounds like a lot more fun!)
Personally, b) sounds like a good choice for me! Its your money, but I would just buy it and not look back. Sure, there is always the chance that you might find it a little cheaper at some unknown point in the future, but weigh that against the fact that you could be enjoying this gun right away.
There are a few of these on gunbroker.com and gunasmerica.com (and there are probably some on auctionarms.com but the site seems to be down at the moment), but even if the actual selling price ends up being a little lower, you will have to pay shipping (UPS or FedEx overnight or 2nd day) plus a fee ($20-$25 or more) to a local FFL dealer just to receive it. If you buy it locally you will still have to pay sales tax, but that is usually cheaper than shipping plus the FFL fee.
