I have a Tasco BKRD30/22. Not the best red-dot, but it works and it is relatively inexpensive, I think it was $30 or $35 from Midway. I find that when I turn the intensity down as far as I can, and still see the dot, it does not bleed/distort as much. One reason for me selecting this red-dot was to keep the package price (rifle + sight) low, so the parent of a new shooter would not get sticker shock. They will get sticker shock when they look at the price of a precision AR target rifle.
He he, I know what you mean about adictive. I started shooting 10m to try it out, and once I got help with my shooting to get me started with the correct basics, I was hooked. So much so, that I don't shoot my sportsters any more. :-(
Yes get a decent set of sights for your rifle and you should be set.
Although take a good look at your front sight, if you unscrew the ring on your front sight you might be able to drop in a clear plastic insert. My Gamo front sight has metal inserts, but I can also use the 19mm Anschutz clear inserts. The one thing good about the metal inserts is that the cross bar can be used as a reference to help align the rifle. You can see if the crossbar is tipped right or left and then you know you are canting the rifle. Or if you cant the rifle, like me, then you have a reference to help cant the rifle by the same amount for each shot. You loose that reference with a clear plastic insert. To me, where the plastic insert works well is on the multi-target target like the STEROID where you have 15 targets on one sheet. By being able to see through the plastic, you can more easily see the rows and columns of targets...and shoot at the correct target. When I last used metal inserts on a multi-target, I shot the wrong target, because the cross bar hid too much of the target, and I did not know that I was aiming at the wrong target. With a single target like a regulation 10m AR target, you only have ONE target on the sheet, so that is not an issue.

I decided that it would be easier for me to just print Gamo clone targets but with different black and white ring colors, since I don't have a larger insert. Then I don't have to hassle with overlaying.
