Remington 870 Combo
Remington 870 (or Mossberg 500) combos would be an option. The 870 is about $360 for the gun and field barrel. Barrels can then be had for around $100 each so he can add a rifled slug barrel or an 18" barrel for HD, or for $450ish, you buy the combo and it comes with the field barrel and a rifled slug barrel.
p.s. I know this is the rifle forum, but thought I would throw out an option...
I like guns.
