firewire vs USB2
Small Dog
I will not try to recommend a camcorder for you as I have not looked into the end of the market that you are aiming at... however save some money....... Jhieminga is giving you some slightly misleading info....
Firewire (IEE1394) is only of real benefit if you are recording in High Definition... which you will definitely not be doing with a camera at £250.
USB2 is not a waste of time and is perfectly suitable for what you will be doing - you will not see any noticeable degradation in quality.
If you find a second hand camcorder that records in HD (tho be wary of the source as that would be extremely cheap for a 2nd hand one at this time) then you will need firewire otherwise any recording you have made in high definition will (in laymans terms), be downgraded to standard definition when you export it into your computer for editing if you use USB 2.
