Stu, Futaba (3VCS or the new 4-something) and Sanwa (Exzes) are the most popular radios in LMP12 because they are more responsive (accuracy and speed) than others. Plenty of 3VCS on the For Sale section, and get it with the 2.4GHz module.
I am wedded to Futaba because it has never let me down. With the 3VCS you can use FRSky receivers that are £23 each and work perfectly. There isn't a cheap receiver alternative for that I know of, so the Hobbyking discount is probably your best bet. HTH
