I've sent parts to Forum members and haven't requested or needed anything in return. It seems that "What goes around, comes around", as I've requested parts in the WANT section and have received several items as "gifts" from members. I once requested a part and received it, but never received an answer from that member as to what he wanted in return. As has been said, I'll continue to help people out when I may have the parts they need. The few trades I've done with people have all worked out very well.
