well for pc hook up, you'll need a digital camcorder. Id go with a mini-dv. the tapes are 1 hr in length (not too bad) but general battery life is bout 45 min unless u get extended batteries. and STAY AWAY from canon, at least the zr series. my first one was a zr200 and it would record the motor noise, so on play back it sounded like there was a mac truck idleing in the background (i went thru 2 of them before I opted for panasonic). but pc hookup isnt all that easy. you'll need a program to capture video and Ive ran into problems with this. another thing, if u do want pc hookup, get a firewire card. much better quality over usb.
pros of mini dv
-small, compact, light weight
-cheaper than dvd, mini dvd
-decent battery life, depending
-same options as most other camcorders
-some mini-dv has an analog input to transfer hi-8/analog sources to digital
-most of built in digital camera, but usually only bout 1mgp
cons
-decent battery life (45 min for stock battery)
-tapes can run bout $5 apeice, but sometimes u can get 6-$20~ on sale
-lot of them will record motor noise, but for like my panasonic, its not that bad
-tapes only last an hr
