Anybody know a good lab where I can have the occasional slide printed?

I shoot 90% B/W but every once in a while, I get a wild hare up my a$$ and shoot a roll of color. I usually take them to my local camera store to print them but they use a digital mini lab which only makes prints up to 13 inches.

I shot this one and I want it printed up real nice.

Maybe even frame it up and sell it.

I would be inclined to print it up myself but I don't have a color enlarger and all the stuff to make color. At this stage of the game, it's not cost effective to buy what I would need.

What's a good lab who can make nice prints? Minimum 11x14 but maybe 16x20 or larger?

This is going to cost me an arm and a leg... right?
