Roland CUBE-40XL pedal question

im looking at a Roland CUBE-40XL online and was wondering if anyone has one and is using a pedal other than the boss pedal that is listed as the accessory for the looper. it seems a looper would be useless without it, and i must have 3 or 4 on off pedals laying around, i dont want to spend 55 bucks on a pedal that i dont need. any thoughts, comments, ect?
