The Sig Romeo 5 is very popular and can be found for around $110 online.I hate to hijack this thread, but on the same subject, what would be a good, budget starter red dot setup? Money's tight lately but the interest in the hobby doesn't die!
Since I have astigmatism, I prefer prism optics. For something in the middle, price wise, I will soon be getting a Primary Arms SLx 1X MicroPrism with the ACSS reticle.

I have had a chance to use one of these on a friend's PCC and I really like everything about them.
They also make a 3X version or there is a 3X magnifier if one chooses to go with that set up.
