I bought my LB12"+ Orion collimator from Bintel earlier this year, and a month later a finderscope for the same scope. The collimator was not in stock at the time, but when it arrived a week later it was express shipped to my door for free.
A few problems with the altitude brake scarring the aluminium bearings, brought an immediate "We'll fix it" by Don. In the next order from o/s (3weeks) the new bearings arrived, N/C!!!!.
I've dealt with Bintel for about 6years now, from small things ($8)to a brand new scope, and I've always found them courteous, friendly and prompt.
My 2 cents. John.
