UK digital printing services

So I've got digital photos to print, where do I send them? I could do without being a member of anything in particular, and I'd like to specify aspect ratios and and finishes fairly precisely. I certainly don't want to schlep around the chavvy high street with memory cards and CDs.

Therefore email/upload to send and letter box to receive.

As well as speed, cost and quality, I'm interested in the way that metering is done, and whether this can be controlled at my end. I'm also curious as to whether there's any integration with my software - e.g. an export plugin for iPhoto. (Jessops had something like that going with Windows XP, as I recall.) I'm not interested in sharing, cos I've got all the Flickr I can handle.

Can anyone recommend anything in particular?

Having built up a short list, I'll do a few test runs, and report back here as I find out more and as the results come back in. If I give a price it's for a 6x4, with quantities in brackets.

1. Jessops photoexpress "Register now" blah blah 20 p, 15 p [100+] +£1.50 or pickup. The annoying ofoto Kodak gallery model? Sharing options.
   
2. Truprint Registration. 10 p + 99 p p+p. Pay in advance facility for cost reduction.
   
3. Snappy Snaps No registration. Based on local stores (you can email the store directly -whoo!) who offer varying services. Mine offers loads of print options (25 p for small quantities). Equivalent to walking in to the kiosk, as no delivery option (cos no payment system, presumably). SS is a franchise outfit, which explains the local variety.
   
4. photobox 15 p each, but lower if you buy credits. £1.50 p+p.
   
5. Bonusprint 12 p +99 p p+p
   
6. dlab7 a sister-outfit of the VAT-busting Guernsey based 7dayshop. (cheap consumables, but mixed reviews in other cases) 80 p to 10 p [100+]. Prints from CD, with restrictions on what sizes you put on your submitted CD. Free delivery (I should jolly well cocoa as you've had to pay to get the files to them).

Results of trials posted here in due course.
