Alasdair - yes, he does have plenty of money in the bank, but he's worried he might give away his location if he tries to get to it while he's on the run. He might be worrying unnecessarily, but like you say, he hasn't got much sense of money and as long as he's got enough to pay his bills, he's unlikely to give it much thought.

Hobbes - I think kativip is the principal source for fake sims. It's hard to find stuff on her site (Cradle of Darkness) but I got most of mine by downloading a couple of city lots from there which had a whole bunch of them included in the package. Close up, they look obviously fake, but they're great from a distance.
If you still can't find them, I've got a file full I can upload to my cloud for you to grab. Just let me know.
