I have to disagree with the following:

The only reason I say this is to have a little variety in your closet. I really wanted an AR chambered in .22 but I decided I am going to buy a different platform to plink with .22
A.) If you're looking for a .22 AR trainer...a 10/22 is no substitution. I have both and although the 10/22 is a fine firearm, it simply does not have the shooting ergonomics of an AR.
B.) The 10/22 is NOT easier to service than the 15-22, not by a long shot. You crack open the M&P, remove the bolt group, clean the barrel/feed ramp and the bolt group. One piece to remove-vs-the systems of pins and crap you have to take out of the 10/22. Again, out of the two, I'd clean the 15-22 hands down before I'd take a 10/22 apart.
C.) I STRONGLY advise you stay away from either the Colt or the HK AR clone...both are made by UMAREX and are like disassembling a swiss watch. Being the same, neither accept AR trigger groups either (something the M&P offers). Again and again the S&W wins out over the UMAREX in reviews for the ease of cleaning...also, the cheap S&W magazines-vs-the UMAREX mags also win out...
D.) While I love the GSG 5 and AK-47 they too are like disassembling a watch. My father had their "limited edition" AK clone and while it was nice, he eventually sold it because of how terrible it was to take apart for cleaning (something you have to do often with .22 LR).
I was going to make my 10/22 closer to an AR via aftermarket parts for use as a cheap AR trainer until S&W released the M&P. i read, and read and them read some more abut the S&W, Colt and HK but eventually decided on the S&W for many reasons...like others here have said, the 15-22 is a fine trainer and a blast to shoot. I'd highly recomend it to anyone.
