Ben,
heres the best answer...
Canon have amazing autofocus, great lenses but are fragile
Sony HDRs are really good all rounders and hold their value.
Always buy HDV now, SD is dead and even if you acquire HDV most camcorders will output SD for monitoring on normal TVs.
Then its down to editing platforms, HDV takes up no more space than SD DV but its best to get out of HDV format for editing and thats a disc hungry game. I'd suggest u use Final Cut Express on a mac with a big firewire 800 drive attached.
Don't forget u need a fluid head tripod, everyone gets that wrong!
Cheapest place to buy, tottenham court road in london. A bit of bartering can knock off as much as a grand!
good luck!!
p.s. don't ever sell anyone elses sail through skype again, he's miffed!!!
