Yep get a used Aimpoint. There are some pretty good deals out there if you're lucky.
The problem with red-dots, is the cheap-o guys are never really going to last through a lot of recoil.
You could probably get a Tasco/bushnell tubed red-dot sight (not the ones with the integral mount) and they MAY last fairly long, but I cant say from experience. I do know that the cheaper ones with integral mounts will shake apart rather quickly.
I may have gotten' lucky perhaps, but the $52.00 Tasco w/ integrated mount that I have has served well on my Norc 870... and while you shouldn't believe most (or even half) of what you read, the Tasco packaging rates the scope for use on shotguns running up to 3" shells...
have you considered the Burris Speedbead?

^there is usually not so big a gap, but this guy also installed a sling adapter between the stock/receiver.
