Mike,
I was just searching to update my list of on-line suppliers and saw your post - your lonely post, with no responses! Sometimes I think the forum must eat a post, because I always ask to read "all unread messages," and yet sometimes I still discover that I've missed one.
In any case, I'm sorry you never got an answer back on your post. It may be that there simply aren't any retail outlets in the DFW area - but the same is true for most of us, wherever we are. Thus, I generally buy all my supplies on-line. That's actually what I'm searching for at the moment - updating my list of on-line suppliers. I'll start a new thread with what I find for the benefit of all ... but meanwhile, I hope you have been keeping up with the hobby. It can be addicting!
