18's on a taco

so i MAY be gettting some money here soon, and i'm wanting to get some 18's (maybe 20's, but i doubt it)but i was just wondering a few things...

(1)i know KMC no longer makes the guidos(sp?), anyone know of a rim that looks like it?
(2)what width&offset range will i be safe with that will not affect my turning, and tuck later on. I should be doing a 3/4 drop soon.

I've never bought any aftermarkets b4 so if i sound like a dumbass, thats y

good luck findin them guidos....they are fuckin hard to find but they are out there...there is a full set of 19's on ebay....wish i could afford them...again
