If I'm not mistaken, this company is the official sony repair center in Canada. I've sent many ps3's there. Prompt service, 8 day turn around on PS3 repairs at the time... Never bought a refurb from them tho...
I'd rather get a second hand ps3 with a receipt from someone on RFD, etc instead. I'm sure there are still bundles for $400 still around, just ymmv on the receipts anyway.
