I agree with the others, the M&P15-22 is a fine choice and you're not likely to beat Walmart's price without a lot of searching. My buddy got one years ago about the same time I got the Colt M4 .22lr. Both have been fine rifles and perform about the same. He got the old version without flash hider and wishes he got the newer model. I got the older 180 degree selector and wish it was like the new one. Oh, well early adopters. The Colt is heavier so your wife probably will like the lighter polymer M&P15-22.
The biggest issue with assembling an AR isn't so much getting the parts together right - it's getting the right parts together.
