Unless you know how to hunt for a bargain that is in top condition Theres one on ebay for £14 top bid atm - think I'll wait for a bit before I get a box - gotta get other things sorted.

hi, that wont be a regulation BFA flyball box, it may be chute, which is different, would also assume you are reffering to a Clix one? if you do get one of these you need to be very careful, they are quite flimsy, you also need to be sure you teach a correct turn to avoid injury
proper flyball boxes do not sell for less than £150, and thats for a second hand one
