We do the kids and my folks. For DH's adult relatives we do a secret Santa with a $120 limit.

Could you suggest to your DH doing a "stealing" kris kringle? Its lots of fun and limits your spend to what is affordable to all. Everyone biuys a gift to a predetermined value and wraps it. All names in a hat. Whoever is drawn out first chooses and unwraps a gift, and then draws the next name. That person has the option of choosing a gift and unwrapping it, or "stealing" the first person's already chosen and unwrapped one. If they steal, then the person whose present was stolen gets to either choose a new gift and unwrap it or steal someone else's unwrapped gift. The only rule is that you can't steal back your gift immediately (you can later though), and the game is over when the last gift is unwrapped. If you all get in the spirit its great fun and can last for ages. We've done it with everything from $20 gifts to $150 value
