Sorry to sign up and ask for help straight away, but I am confused and desperate!!

I need a camcorder to use for filming horses indoors - friends having lessons, jumping at shows etc. so light is going to be low as most places use fluorescent some use halogen. I will be doing some outdoor as well, but thats not going to be a problem!

I need to do up to 50-60 mins at a time, possibly 5 hours in a day, and be able to download to the computer or (preferably) copy direct to disc as well. Times are maximum usage, but I thought it best to allow for more rather than less!

Battery would need to be pretty strong I would imagine although I could have a spare and recharge one while using the other.

Budget is around £600

I have looked on Jessops, PC World, and other sites, but I have just ended up confusing myself even more and I don't trust salesmen in shops to reccomend the best for me rather than best for their profit

Thanks for any advice
