I've just bought the GS3 and am happy with it.
No USB which would have been handy.
Lots of options etc on the menu system, too many even.
It can take photo stills in the version of 7 second recordings on the tape, so easily edited later.
The few functions it misses on against the more expensive models (ie, memory card), are minor in my opinion.
This is my first camcorder, so I couldn't say how it is against any others.
I bought a firewire card which came with a lead from
www.dabs.com in their value section. £13 incl. p&p.
A Seagate Barracuda IV 80Gb harddrive for the pc for editing, from
www.komplett.co.uk for £83 incl p&p.
I'm now looking to get Pinnacle Express editing suite to round it all off and I'd say you'd have to spend a lot more on better cameras etc to see big gains in overall quality.
I am a home user only though, so it depends on your needs.
I bought my one from
www.empiredirect.co.uk for £498. RRP was £650 on the high street at the time, but I think this particular model may be discontinued in the near future, maybe.
However, do a search on the forums as there is another supplier who's name I can't remember, that a lot of people rave about for price, service and general customer satisfaction.
