These days there are a lot of folks contracting to have optics made and their name put on them. Companies who are not really in the optics business but who seem to think it might add a bit of profit for them. The question you have to ask yourself is this:
Will they be around later when I need warranty repairs?
For me the question is enough to cause me to shy away from such companies and stay with those who are strictly optics companies and have been around long enough for me to have confidence the answer to the above question for them is a resounding yes.
