I recently ordered prints from iTasveer and I am very impressed with the overall experience. The print quality is pretty good and the website interface and upload page is impressive and very user-friendly. The print costs are the best I can find at the moment.
I will definitely be recommending this website to my friends. The only thing I was not happy with was the Aramex courier service (they returned the shipment on first day without calling and delivered only after three days).
Note that iTasveer shipped it next day after I ordered.
