I, for one have been keenly awaiting Belkin's Lego cases, simply because they're Lego.
Your tastes may differ -- and that's fine -- but as soon as they were announced I wanted to know what they'd cost. Belkin's announced local availability and pricing. As of today you should be able to pick up a Belkin LEGO Builder case for iPhone 5 for $39.95. Lego to stick on to it will cost extra.
