If you choose the Omega, buy it new. If you buy refurbished, the warranty is minimal.
I purchased 2 of these in recent months. Absolutely pleased with "the view." they are bright and clear. However.....one of them had very erratic adjustments. 10 click might move the point of aim 1/4 inch this time, then off the paper next time. The vertical adjustment finally froze at the upper limit, all under finger pressure, no tools were used. It is currently at Nikon. Their communication has been excellent, and they are repairing it at no charge.
Can hardly wait to see what the rest of the story will be.
