Yeah, I like the way it is too. I feel that dividing it up would cause confusion.
Everything there is radio related in some way (occasionaly some junk sneaks in but is quickly moved to another thread of removed completely).
I think if you added a "general" for sale area for non-radio related items, you would see more scams. I thought about if we had some type of feedback forum it would be nice, but that too would likley get out of hand.
The system we have now works very well. My vote is to leave as is too.
