I've done various levels of desktop support over the years... To be blunt, I'm sick of it

I'm interested in Linux, and would like to pursue a job in it one day. I know experience is king, especially with Linux, but would be a good cert that would perhaps help to open a door?
I don't think RHCE... since I obviously don't have the hands-on, and that's not really a entry level cert.
I know there's either linux+ or the LPIC, but if you happen to do a keyword search on any job board, you get very few hits. (at least, where I'm looking)
..just looking for opinions here.
