axyz is a good option, Do not buy Emach brand new, used ones are good, as I used to build and service them. as for budget, without atc option, a 1250 x 1250 m/c will set you back 14 to 18k brand new, used around 4.5 to 8k. with ATC add another 1 to 2k on used prices.

Keep a look out on www.lotsurf.com ( or co.uk ) they do have them come in at times.
