Value Poster Printing

Looking to print 18x24 and 11x17 posters, quantity range from 20-200.

I found www.shortrunposters.com on another thread.

Any other good websites for poster printing?

Well, 11x17 or 12x18 can be printed on many digital toner based machines and come pretty cheap, less than 50c most likely, but 18x24 should go on wide format printer, in my understanding. Anything out of inkjet based technology... (they want $5 for 3 sq. foot image) - it is $1.60 per sq. foot, how much better do you think it can get? This is clearly wholesale prices offered to retail market.
