knife collecting tips

I have several folding blades right now and I want more legal fixed blades to add to my collection. Anyone know of good places to go to in dfw or to search online?

My husband is a knife maker he sells most of his knives on Bladeforum.com

It is a cool site lots of excellent makers at all levels, making all sorts of knives. You can talk to the makers and ask questions. I would highly recommend it! My husband's name is Will Crump
