RE: Ridgid 6 1/8 Jointer Model JP0101

I am in need of replacing the cutter blades on the above Jointer, and have heard that this model has been dropped by Home Depot. I have also heard that the replacement blades from HD have not received rave reviews because of chipping.
Does anyone have a good suggestion for replacement blades. I have seen some sources on the net, and they all ask for exact size. As a novice, I hate to take the blades out for measurement, and be out ...
