This is a good price for this very good product.
I have two different ones, one for my walk about bag and another for the Flexbody and, if I can find one in good kip at a bargain price, a Hasselblad bellows.
If you have more than two Hasselblad C, CF, CFi, etc, lenses or want to use 4" or 100 mm gel filters, this is a good piece of gear to have to hand.
I'll go so far as to add, for cameras other than Hasselblad, adapting these might just be worth the effort.
IMO.
