I like the IPV4... I've held one in the B&M, and it wasn't a brick, but was darn close I would love to have one, but I think I'll either wait for them to really drop in price or my preferred choice... hold out for the IPV D2
I agree the mirrored OLED screens are dim in the sunlight, but I've yet to find one that isn't difficult to read in bright light. The black ones are much easier to read, and I think that is why I like my Cloupor minis and IPV-mini V2 so well... I can read them in places other than dark room
