I found a used vp150 center chanel for 180.00 all the pictures look good no damage, just a minor scratch on the back.

Do you think it's worth it I do not have the chance to listen to it

Thanks

How old is it? If you have Axiom speakers for your mains and you need a center channel, then yes you should consider it.

Yes I have m80s which we have been using for music only but I am purchasing a new 54in plazma & denon 3808ci
just curios it is a fair price

It retails for over double that so yes it is a good price. The caveat is that buying from the used market it will not be covered under warranty. As long as you receive a fully functional speaker from the seller, then yes it is an excellent deal. Get an idea of what the seller is all about before moving forward. Make sure the shipment is insured and ask how he would package the speaker(limit the chance of shipping damages). A cardboard box, garbage bag and packing peanuts won't cut it.
