I need a new handle for online gaming. Any suggestions?

Hello everyone! I was using the handle "somberfire" for a while on Xbox Live and CS:S, but I recently discovered that there was a very good (and moderately well known) Quake player that still uses this handle, so naturally I want to change my alias. I've been searching names on XBL, but a good deal of them are taken. I've been trying to keep things simple, as in two well known words combined, however I haven't had much luck. Any suggestions? Thanks :-] .
