A D70 is pretty old for a DSLR, I probably would've sent him to the D40 at the same price point just because it's a bit newer. That said, he'll have cheaper options for good lenses.
He never said (I don't think) what he's USING it for. But assuming it's action shots of paintball, the 1/500 flash sync of the D70 will serve him well.
OP, here's a sleeper lens suggestions: the Nkkor AF-D 70-210mm zoom. The "D" (not just AF) version can be had for under $200 and was INSANELY fast focusing. Great for tracking action...much, much faster than the budget 55-200mm VR and also far better built. Link to lens
