Good cheap 3D printing service in UK ?

[perdrix]

Googling around to find a 3D printing service to print the front panel for Jared Cabot's TM500 Tester.

Lots of expensive ones and the few cheaper ones I found so far seem want to hit me for a lot for postage (e.g. £8 to print then £14.50 p&p).

Thinking white PETG or glass filled nylon?

Any recommendations most welcome.

Thanks, David
