Gill at Squadron Prints did some badges for the largest FJ Sqn in the RAF last year. Looking on their website there's little mention of patches - so maybe they've ceased to do them. This would be a shame as they were excellent quality. We had had some average service from Terrane, which left the impression that they didn't need our business, so we jumped ship. Sqn Prints is very friendly and very reasonably priced, however, the size of the initial order may put some punters off.
