Why is the Limey a fair bit more expensive than the Ice given the weights and geometry? If given purely the stats and the pics, I'd have thought the Ice would be the 'higher level' frame? Anyway, you've done a good job on both
I'd just like to say I've not had any problems with T-UK, though have only had 2 orders from them. Both were correct and arrived next day. I do, however, have friends who were owed money (about £50) for months on end before anything was sorted.
Could you grab some old/cheap/broken tiles from somewhere along with a bit of plasterboard and have a play around with it before you go balls out in someones home?
