Okay, so this was £3.79 at a local garden centre, and I've been eyeing it for a while:
Came in about twelve parts and slotted together reasonably well. The only bits that gave me trouble were the four embellishments at the base of the tower; they kept popping out, so I took a glue-stick to them and stuck them in place. That aside, it didn't take very long to assemble and the instructions were clear and to the point. I do with it had come in a few more pieces so I could have presented it with 'battle damage', but I'm sure it'd be easy for anyone handy with a knife or dremel-tool could probably add a few touches here and there.

A determined enough modder could easily get some cheap watches and turn it into a working clock-tower for that added realism. Just don't ask me how to add the chiming of the bell...
