Probably at about 200 for repairs and shipping. Maybe more to buy a box at USPS. New ones 399.99. How long are these units going to last. If I get footswitches upgraged, how long is going to be for other knobs and such go bad (I gig mine regularly)? The model select knob for the lst FX is getting a bit hinky too, so that concerns me (not to mention that all of the knobs in that section were stiffer to turn since the day I bought it). My other option is to buy a programmable loop/selector and individual pedals. Won't be near as useful but at least if one pedal goes down, your whole rig isn't shot. And it's cheaper to replace one pedal than to send an entire unit out for repair. But it's probably going to cost me what the cost of the repairs are for a cheap programmable looper, that may be no better than the Line 6 stuff - then I still have to buy pedals. IOW, if I make this investment in the M13, I want to see decades of use out of it.
