Speaker system recommendation to buy and Receiver

How much do you guys think this is all worth/how much would you be willing to pay for it all used?

The offer is $120 for all.

Also are the speakers any good? I'm thinking about buying this set just for the Subwoofer and receiver, because i already have 4 full infinity speakers.

Speakers Model# NS-AP5705
Sub Model# YST-SW012
Receiver Model# VSX-816-K

If everything works and in good condition seems like $120 would be fair. The receiver is from around 2005/6 and sold for $299.00 but with sub and speakers, not bad deal. Also, depends on if you will use the receiver for surround and will it do all you need.

I agree with Pea. Just check to make sure everything is functional if possible. I have a friend with a similar receiver and sub and it adequately filled a decent sized room with good sound. Not very familiar with the speaker set though.
