How long to plan on keeping the car? That right there would be my deciding factor on cost.
Are you going to do this swap yourself? Being in an apartment I doubt it but you may have access to a garage somewhere, I dunno.
My thought is this- if you plan on keeping the car for the longhaul and don't want to pay someone more than once to R&R my trans then I'd go with the TEP trans. Dave seems to stand behind his work. Shoot him an email and see what he recommends for you, it may be possible to save some cost depending on what options he builds it with.
If you just want to keep it running long enough to sell shortly then I'd go with the cheapest option that has the best warranty and be sure to sell it before the warranty expires that way the buyer doesn't get stuck with a nice car with a POS trans that was supposedly "rebuilt". Been down that road before and it sucks. Just my .02
