I've done 4 AG batches now with my home depot mash tun (cooler and SS braid). For what it's worth, I don't see any problems with the set up. In my area, they sell the line as simply "supply line" (toilet, sink, dishwasher, etc.) The plans for an MLT recommended a 12" line; I used a 16" and it fits a 10 gal cooler with only a slight bend. I haven't had any issues with it collapsing or allowing sediment through, nor have I had any issues with it floating up in the mash. I am careful not to stir too deep and I am careful when cleaning it. I dont know what bazooka tubes are going for, but the the money, I would recommend the supply line first.
