I got mine using cheats. I was a cheater back then, and I'm a cheater now.

I'm not much into cheating, but a bit of manipulation now and again, that I can do!
I found that wishingwell very tricky, so, I took a sim I no-longer wanted, who owned the well, and Um, dare I say it, let him/her have a wee accident, so that the home, and the well, were left behind on an uninhabited lot. You could then edit the lot until it was affordable by a new sim, move your family in to put the well in their inventory and then moved them to the lot you wanted. The problem in Sims 2 was that when you moved a family out, any posessions left behind just disappeared, but if they died, everything was left behind. But, once you had a lot with a well, all you had to do was save it to the bin for multiple reuse. Actually, with the new moving system, there's no need for the accident if you wanted to make a "gift lot". Fill the bookcase, stuff a chest, I guess you could leave a fortune behind and, bookcase and chest items would not register in the lot price. But, moneymaking and aquiring special items is so easy in sims3 that it would, imo, spoil the game.
There was another little trick, rather a nasty one, that I did occassionally. I found babies, a pain, and adopting children was very hit and miss, so, I would make a single mother and the child I wanted. Move them to any horrible home and then have mother neglet the child so that it was taken by child services. When ready to adopt, the child would be the one offered for adoption.
There was a beauty in Sims one too. If you made a sim, and left all their trait slots empty (negative), then bought the chemistry table as soon as you moved in, there was a potion that reversed all traits which you could usually get after 3 or 4 attemps, hey presto 100% positve traits; No, grumpy, lasy, bad tempered sims!
