thanks for all the replies.

If as Luke says I can get the zdz for £315 (sounds like a brilliant deal) then I'm very tempted. Although it almost sounds like too power much really.

I looked at 3w but the weight is an issue at our field, our strip is quite small so getting it down may become a bit of a problem unless the wind is in the right direction.

And no I cant wait for the Extra ! From what Glen was saying on the phone its not going to be ready for while yet.
I'll just have to get that one next year
