A tenth to a twentieth the price of the usual models from Jamestown, Dr. Shrink and so on. Certainly the $500 ones are elegant, but this looks similar to the $250 one for a tenth of that price. Makes ya wondah. I have the no-longer-available from Dr. Shrink cheapie and get two years out of a 24 x 85 roll. Plus the door, strapping, assorted tapes and ends for the 2x4s. I've been buying through SailorSams who had free shipping two years ago.
