Rudy - CALL YOUR BUD!!!
Better yet, odds are better than anything that they're registered with at least one of the following places: Macy's, Bed Bath & Beyond, Linens & Things, Target, and/or Home Depot/Loews. You can check online. It's easy. Even you can do it.
I would check the registery before you decide to make up your own gift. My friend registered for a grill. Men can buy a grill without fear of being girly.
If there's nothing on the reigstery that you want to get them; I vote for cash with a simple card.
