Thanks for the advice chaps. With regards to the make of bike. I have been looking at the beta just because i've read good things, and quite like the look of them. When i rode trials, it was on a new gasgas 125 which was a fantastic little bike.
With regards to kit, the budget for that shouldn't be an issue. I've ridden alot of mx over the years too and the kit all seems quite cheap in comparison!
I'm certainly open to other brands and would certainly consider both gasgas and beta. Like you say, i probably need to try both the get a feel for the newer bikes.
I think i'll keep an eye on ebay, biketrader and the classifieds here to see what crops up!
Thanks again
Hugh
