josh just get a minidv player. dont worry about HD. i have a drc-hc21 that would hold you over good. get a higher model number if you want more options. but a sony minidv will be about 300-500 dollars.
the sony hds are not that good. the technology is too new for consumer level hd cameras.
if youre willing to throw down a semi-serious chunk of change, look into the 3ccd minidv cams. they are near-broadcast quality. only people who know what to look for can distinguish between 3ccd quality and absolute broadcast quality
what kind of sony do/did you have? i never thought a cam could be incompatible with a computer. cuz it should just extract as an uncompressed avi file, which is what any minidv tape should be extracted as.
if youre willing to spend some cash, the panasonic 3ccds are supposed to be good stuff and under a $1000.
