My band has decent (not great but decent) backline equipment, but all of the PA stuff we use is borrowed from our church. We don't play out all that often so borrowing the stuff isn't a big deal now, but are looking to gig more and would like to aquire our own equipment. The guy we borrow the mains from (Peavey Sp-5s) is is buying new speakers for his southern gospel group and has offered to sell them to us for $250 for the pair. I know they work and work well as we used them this last weekend, but they are probably four or so years old. We will have these for a while so are there any issues w/reliability I should know about? Good deal?
