I think about 6, not counting the platic one with built in speakers my mom bought me because she knew I liked listening to records.
Panasonic - (part of all-in-one receiver/tapedeck)
Pioneer BD
Realistic DD
Kenwood DD - (forget model, but pretty heavy)
CJ Walker BD
Linn LP-12 - This started as a Valhalla, but has been cirkus'd, Lingo'd, and currently has an Akito II and Monster Cable Alpha One cartridge (recently aquired right here).
