Fuel injector cleaning serivice recommendations?

I recently picked up some used Mazda S5 non-turbo fuel injectors (N350-13-250) on Ebay. Looking for recommendations on a good cleaning & flow test servicing shop?

I used RC fuel injection to clean mine several years ago. IIRC everything went good. Injectors are still in the car and working fine.

Ok, thanks. I'll checkout their website. If I recall, Engine Labs, a email newsletter that I receive, recently had a article about RC and their injector services.
