I picked up a female firewater from that expo back in February, and I got her for $50.
There will be several leo breeders there, and I recommend checking out Bryan Jett's (Jett Exotics) table. In my experience he has the best looking geckos for the best prices.
You can probably buy a baby normal for that price. It really depends on the breeder. A lot of times the prices at shows are very reasonable. You can probably find a really nice looking morph for less than $50
I got a few from HISS and wasnt dissapointed and they do have some normals for about 20 but im sure theres plenty of other people that will have them there and you should be able to find a few for good prices. Whens the show, i usually try to make it but havnt looked it up lately.
