My last impulse buy (note to self: stop buying stuff) is this fella, a Mamiya RB67 Pro. Came in the post today off eBay with a 90mm lens, a waist level finder, and a 120 film back. Brilliant!

However, it's missing the focusing screen, which effectively means I can't take pictures because I can't compose or focus shots. Until I get one I won't be shooting with this.
