Just bought a T-1 today and threw it on a Seekins mount. They are tough and light. If you don't need NV capability or a level of waterproofing greater than 15', you can save some money by going with the H-1. GG&G offers their optic-mount combo and it is the cheapest I've seen anywhere. Its actually cheaper to buy the mount/optic combo from GG&G or LaRue than it is to buy just the optic by itself.
Also, the GG&G mount facilitates Butler Creek flip-caps.

Why don't you try out the Bushnell TRS-25 first which is $85 on Amazon and works very very well before you drop $400-$500 on something you might not like. Then if you like it and you want the best sell it here and buy the Aimpoint.
I just bought a Trijicon RMR for a AR rifle. I was kinda worried if I'd like it but after installing and using the sight, I really like and would recommend it.
Aimpoint probably top of the pile, but also pricey. I have one and love it, but I also have 2 Doctor Spectre's that are equally impressive if "micro" isn't top of your priority. Doctor's are equally clear, but 2x weight at 1/2 price.
