i'm guessing monthly maintenance is not exactly a high priority in the tropics either
how about a 250cc 2-smoker ? They aren't too good on mileage but damn near unbreakable in the long run
I've got both, the gen Pro Divers are really nice but rather delicate IMvHO
If you like to 'strap' down the case real tight, get the rep since the gen will look beat-up a lot sooner
