I just bought the JVC HDD camcorder. It has a 30G Hard drive. WELL worth the money! I think JVC is the only company making these camcorders, at least that's what I was told. I love this thing. It also has a built in 1Mpixel digital still camera. There are some models with better still image cameras, but that's the one I have. Do your homework on them. It is WELL worth the money! Good Luck!
No, JVC is not the only one. Sony has one, the DCR-SR100, and there are several other brands that record to memory cards.
But be aware that buying a camcorder that records in MPEG-2 will give you a lot of problems when you plan doing a lot of edtiting...
