full-color high res gobos in a showgun

OK, so a client of mine wants to do a custom glass full color high res gobo through a moving light, but wants it to freaking pop...I mean just absolutely pop. So my two options, in my mind, were a showgun or the new mac.

In the humble opinion of those on the forums (including HES), how long would a full-res full color gobo last in the showgun or the showgun 2.5? Could I get a few days out of it running at 10 hours/day? A week?

Thanks.
