i picked up a soldering kit from geekhackers.org (the kit i got is now sold out). it was a great starting point, and is still suitable for majority of my soldering/desoldering needs. i found a few old wyse keyboards, which were good for soldering/desoldering practice. after i desoldered a few old keyboards that i didn't care about destroying, i was able to disassemble my poker and put it back together without any issues.
if i had to start over, i would get a soldering iron/station that has an adjustable temperature, such as the hakko FX888D.
just my two cents
