I find normals around here (Denver, Colorado) from anywhere in the range of $15 to $40 depending on the pattern and coloration. I got my normal for $20 and I think she/he is stunning and getting better every minute.
I say if you can pick up a good healthy normal for $15, go for it. Just make sure it eats good so you don't take home a problem feeder or worse, a non feeder.
Good luck
