I'll be interested in replies from other folks. I would guess that there will be 75 -100 or more fine rifles in your price range and for sale, plus pistols, knives and many other items. Don't forget the auction items. Not many western or later fur trade rifles like Hawken, Henry, Leman et al. Eastern arms, early to late, with more iron mounted rifles than ever existed in one place before. Several friends go there to shop, just as you are considering, and come home happy - either with a rifle and/or with one on order. Promoting the work of contemporary builders is why the CLA was formed, and buyers are definitely welcome.
Some builders and fancier rifles will cost a little to a good deal more. Some deliver finished rifles to customers at the show, take new orders and pick up parts, and a good deal of trading goes on there.
Yes, there are display tables, where buyers like yourself share what they have assembled over the years. Maybe you and your friend will have such a table in the future. Be sure to walk across the lobby to the displays of original rifles. This show is a great combination of old and new. You'll probably come home with a rifle, meet many builders, maybe line up a custom order at some point, and who knows??
See you there and have fun.
