Alternative to Photobox for large panoramic prints ?

[NewNameNeeded]

In the past I've always used Photobox for 'standard' prints and your more typical enlargement sizes (but will give Blurb a try for books following the recent thread).

However I took a few panoramics and other shots of Edinburgh recently which I'd like big prints of that Photobox doesn't do (so for instance the biggest panoramic print on Photobox seems to be 20" x 8"). I'd like something at least twice this.

Can anyone recommend an alternative that offers similar quality or prints (ideally at user defined sizes)??

Thanks in advance,
Matt

Go for canvas, Fluid Images (Tim) would be my recommendation
