Welcome Visitor! Please take a few seconds and 
i used a D30 on my SAS. but i have a b2 with a 2.9 in it. i dont plan to wheel mine hard either, just use it for hunting, camping, maybe a light trail every now and then. i chose it for a few reasons.
1) cheap for a complete axle-paid $150 for mine.....plus, i can usually find 2-3 for sale within 25 miles for less $100 around here if i were to need parts. i plan on buying one down the road to have the spare shafts.
2) can be found easily in a matching gear ratio for my rear axle
3) same wheel pattern
4) lots of parts at stores and on the web
i think i spent around $600 to do mine, including the price of the axle and metal to make the arms
