Wanted: Good iPad 2 parts supplier

Hey guys, I run an iPad repair company and have been getting pretty good service from my parts reseller for about 2+ years now. Unfortunately, over the course of the last 5 months or so, the quality of their parts have become drastically worse; digitizers specifically.

About 75% of our parts end up getting returned to the parts supplier due to streaks on the glass and/or grease smudges around the edges of the inside of the digitizer. Fortunately they take them back and replace them no questions asked, but the replacements they send are just as bad and we still have to send a majority of those back as well.

I am wondering if theres other people here that have good relationships with parts suppliers that they would be willing to refer to me. We usually purchase the full digitizer assembly (w/ bezel, home button included). Any help would be great and I would be happy to let the suppliers know that you referred me.

Help me, iFixit community. You're my only hope.

Thanks.
