I'm looking at one for my soon to be 8 year old also.
The Mission Menace and the Bear Apprentice II are the ones I'm considering for him.
The Menace will go down to a 17 inch draw length with a weight range from 16 to 24 pounds and the Apprentice will go down to 15 inch draw with with a weight range from 15 to 30 lbs with the 50lb. limbs and 21 to about 40lbs with the 60 lb limbs.
It all depends on how your son is built. Mine is small for his age ( I measured him between 16 and 17 inches) so the Bear Apprentice will fit him better now and will still have plenty of adjustment as he gets older, if I can find the 50 lb version. So far all I have found are the 60 lb bows.
The Craze specs show a minimum of 15 lbs draw up to 45lbs at that minimum 19 inch draw length, which is a lot of adjustment to play with if the draw fits him.(Too long of a draw length will start all sorts of bad habits, ask me how I know
)
All three are basically the same price, just at or below $300.00 although the Bear comes with a Whisker Biscuit and sight included, the Mission's are for the bow only.
I have shot Mathews bows since they came out and would normally lean that way, but the Bear looks like a good deal for a young person starting out.
