I feel kinda silly posting my own as an example, but here goes: http://www.endofunctor.org/~rpearl/resume.pdf
Are there any particular difficulties with switching from LaTeX to XeTeX?
I actually did my resume with LaTeX, but then became too lazy to update it. Now it's somehow a year out of date :P. (A year is a lot of time for a college student...) Seems like the perfect excuse to redo it and a great time to try XeTeX.
It is based on moderncv, hacked up a bit, but I think that template still looks quite similar to what I have.
My approach was to eschew flexibility (even though LaTeX is amazing at it) in favour of aesthetics. Since I don't plan on updating it for the next few years, I decided to go crazy with tweaking the positioning of things until they fit just right. It would've probably been a bit easier in a DTP app like InDesign, but I try not to use proprietary software if I can help it, and I didn't want to waste time finding out whether Scribus was up to the task.
I'm a bit embarrassed about the source, because I didn't bother with defining styles properly and used quite a few hackish /vspace{}s instead, but it's good enough for a document only I'm going edit.
