Like you I have no complaints with PSA. I'd go that route with kids, depending upon their age, they're interest, and how likely they are to be competing. Plenty of other places to use your cash (especially for kids) and you can always do a match quality build if they or one of them becomes interested in match shooting. Plus down the road, in the AR market, much easier to unload a PSA then a high end build. JMHO
