I don't race at that club but if you are after a buggy hold off a week or two and the market will be flooded with 2nd hand RC10 B6.1's as the B6.2 is out soon but for a beginner the B6.1 will be an brilliant bit of kit.
The B6.1 is probably the most popular buggy in the UK at the moment, also 2wd is cheaper and easier to maintain.

Motor wise all buggy clubs seem to run brushless, they are more reliable, master and easier to maintain.
Clubs normally group racers by ability so if you turn up and say you are a new driver you will be with the slower racers.

Again don't know about that club but from what I can tell most clubs work the following way:
You pay for BRCA membership yearly which you must have (your insurance)
You can choose to pay club membership most clubs give cheaper race day fee's for members as well as other perks. Bury where I run give you rostrum access for the outdoor track as part of the membership as a perk.

I started racing last year after a 17 year break so if you have any questions give me a shout so you don't make the mistakes I made.
