I dont know how tall your boy is but the Samick Sage is as cheap as chips, 62" recurve, limbs jump up in 5 pound intervals and are also cheap as. I bought one years ago and it's never missed a beat. No tools required to remove/attach limbs either. They're all decked out with attachment screw points so you can screw on any bow quiver, sights, stabilisers or even take them bowfishing (mine's had a few ocean swims).
Did I mention they're $130 bucks? Great way to get a cheap bow to move through poundage on and then when he's ready for a really nice US made bow you could donate it to the kid down the road or keep it as a back up bow.
