Most SSDs will work. My current recommendation is the Samsung 830 series. The performance increase is amazing. Its like going from a bicycle to supercar. Its also addictive, at some point you'll want all of your data on one and be thinking about how to save up for a model large enough. 

My feeling is that after you have the capacity that meets your needs should consider

(1) compatibility (what good is it if it won't work in your system);

(2) reliability (what good is it if it fails);

(3) warranty (these things are expensive, and you might like to have one for 3-5yrs);

(4) power draw (some are power hogs)

(5) speed (all current gen SSDs are super fast, and the T500 won't be able to take advantage of the faster ones out there);

(6) what comes in the box (they normally come either as a bare drive, desktop kit (cloning software, mounting brackets, screws), or laptop kit (cloning software, SATA to USB cable for cloning ease).

Some are known to have less compatibility issues. Some are faster than others, and you can't really take advantage of the fastest ones in the T500, but they fallback to slightly slower (and still super fast) operation gracefully.  It seems to have good reliability and compatibility. I recommend staying away from OCZ, as I've heard of too many nightmares with them. While I used to the like Intel 320 series, they had some issues when first introduced into the market, Intel claimed they were fixed, and now those issues seem to be popping up again.
