I think I'm using the same supplier as well … after all, there aren't too many places around that print slipmats with these specs and features. I've printed 4000 or so mats with them over the past 5 years and never had any issues. Communication has always been fine as well, the printer has been away on holidays a few times this year which impacted communication a bit, but everyone is entitled to go on holiday from time to time, can't hold that against him ;-)
