Personally, if you are gonna go plat, I would just go plat 4 life. Its a once time thing and you never EVER have to worry about it again.
Since you are only here 4 months, I might hold off on it until you get back and if you are still interested in the place when you come back, go plat for life. Hopefully George will have a deal like he has going on now when you get back.
Good luck.
