Due to the unfortunate loss of a focus motor on a DA* 50-135 had my first opportunity to deal with Sun Camera. Although apprehensive of repair facilities, simply stated the experience was excellent. These folks are a joy to deal with.
Upon arrival, the fellow at the counter did a few cursory checks of the lens and quoted a repair price.
Happy to say, the lens was in late Tuesday afternoon and ready for pickup on Friday afternoon. Further, the lens has never seemingly worked as securely as it does now...it just feel "right" now!
For clarity, I was never treated badly when getting previous service repairs done at the local Pentax facilities (before closure) but these people at Sun seem to have a more down to earth (non-corporate) approach to meeting the customers' expectations.
I'd use these folks again.
