Honestly, buying the SE and modding it later is probably the best option for your situation. As far as I know, the only difference between the Sanwa-modded SE and the default TE is that the TE has got a sturdier base, which really isn't an issue at all. The default buttons really aren't as bad as everyone makes it sound, I've had my stick 6 months now and only had it constantly stick on two buttons, which a quick disassemble, pop out the button and jiggle it around a little bit fixed flawlessly.
