Hey there everyone, I bought some stuff used, in perfect condition. Here is the list:

-Pioneer VSX-D509S A/V Receiver
-12 inch Miller/Kreisel VOLKSWOOFER Sub ??? Is this a decent unit?
-SONY TC-WR97ES Tape deck
-SONY DVP-S360 DVD player
-SONY SLV-640HF VCR
-SONY CDP-C87ES CD player
-tons of cables, optical, RCA, and S-Video etc..

Ok, so I got this all for 500US$, and I know that each piece brand new would total far more than that, but I am wondering if any of this stuff is still good? Has anyone had any experience with Miller/Kreisel? Is Pioneer good at all? I am a total audio illiterate and would appreciate some comments, I would also appreciate some advice for my upcoming speaker purchase, I only have the subwoofer, so I need to get a solid pair of fronts, or maybe a decent surround setup. Thanks!
