I've been looking at getting one of these in my advanced age to carry around cameras in an accessible place, without putting too much wear and tear on me and not being afraid to drop expensive camera gear. I have used neck straps in the past, but as i switched to a smaller 1" sensor compact, I think i still want something that makes the camera accessible. I wear backpacks all the time so this seems like it could be a good compliment.
Brand new, the unit is $70. If you use eBay today with the PRONTO15 code from Best Buy on ebay, it's only $50.95 (subtracts ~$8 with the code - your tax will vary and shipping is free; the item is listed as $55.99 so it's about $48 before tax). It's listed as Open Box Excellent - that coupled with the fact that the reviews have said this is really physically well built and i don't really care about its cosmetic appeal make this seem like a good buy if you're in the market for a non strap carrying system for your camera.
The reviews on this relatively new product (this is the 3rd version of this product) have been pretty solid:
The description in eBay doesn't specify it is version 3 (V3), but item description (MPN:CP-BK-3) and photo appear consistent with V3 of this product.
