Well, have fun at the show.
If U want an A/S, be aware that they are only being imported in very limited numbers. They stopped last fall. Then, started reimporting the A/S around Spring 06. The A/S is off of the Walther website again, so they may have once again stopped. I don't know.
If U find an A/S for under $600, I'd get it as soon as U see it.
