Nice! I found a HSU Research sub at a Goodwill for like $10. It was a little rough on the cabinet (nothing horrible though, just some nicks at the corners and scratches, the speaker and surround was still in great condition), but worked great still (no blown amp or anything). I cleaned it up and sold it on Craigslist for like $175 (it used to sell for like $350 new so I didn't feel like I was totally ripping anyone off).
I got some old Bell + Howell projector for $1 (had a $60 tag, but it had the color tag that was all $1 that day). One of my sister has old cameras and stuff for decoration so we gave it to her (even if she didn't want it she could take it back to Goodwill and they'd give her $1 for it). It was in good shape but had some residue on the film feels that we had to cleanup. No film and no idea if it works fine or anything so it might be broken.
