HELP!!! Need to get a wedding gift quick - ideas???

[Betarulz!]

So I'm going to my first wedding as a collegian - no doubt the first of many. It's for a girl who was my boss this past summer at space camp (she graduated from UNL in May and is getting married to Sigma Nu's former president). Anyways, the wedding is tommorow, and I would just like to be on the safe side in case a lot of my co-workers show up with gifts, plus since she'll be my boss next summer if I go back to that job it doesn't hurt to suck up a little.

Anyways I'm totally clueless as to what I should/could get them. I don't know where they are registered nor do I have unlimited funds. So anybody have any cheap ideas? I was thinking something space related since she works at the Kansas Cosmosphere and Space Center as a space science education, but it's hard to find such things in Nebraska, besides she could get pretty much anything down at the Cos. So I'm SOL as of right now. PLEASE HELP ME ASAP!!!
