Printing panoramas

Does anyone have recommendations for online printers capable of printing very landscaped images? The only sites I can find have fairly fixed aspect ratios on offer. I tried ordering one print on a large size from snapfish, hoping it would just be scaled horizontally, handily it was scaled vertically so I lost most of the picture.

in addition to the comments replying to my similar question in the link Dan has put above:

I have not expanded canvas yet but will be next time I want a panorama from snapfish. It's not difficult to do. However, I have used DS Colour Labs and their software you download to your PC to manage photo uploads does let you do what you want. I have printed several panoramas this way. You put the photo inside a larger print like say a 12x8 for example to print a 12x5 panorama. I was very happy with the results. The link below shows a panorama I printed from them which came out perfect and is now framed on my neices wall.

I haven't actually got round to using them for doing this yet, but Metro Colour Lab do panoramic. If you ring them up, they will quote for whatever size you want (ie bigger than the ones shown on the prices page).

As I say, I can't speak of the quality, but they are a company I used to send my slides to for processing in the (good old ) film days, and was very happy with their service then.
