OK, so I'm foolishly considering releasing a 7" single. Various factories have been suggested on these pages, including:

http://short-run.co.uk/
http://curvedpressings.com/
http://www.discmanufacturingservices.com/
http://www.gzcd.com/

I can compare the *prices* fairly easily, but does anyone have any views on the *quality* of the different suppliers? Are they all pretty much the same, or do some make better vinyl than others?
