ive seen them go for as little as £20 and up to £100 + the main problem i had was finding a controller as mine has cruise and had a lowline, because i was having the highline fitted aswell i had to get one that could do cruise, highline and MFSW, in a way i wish id got a flat bottomed one now but they can make silly money imho, i just kept an eye on ebay and got one from there
