What certification to pursue?

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.

what you need is, get a decent book(s) on linux administration, install linux on one or more machine, and start reading and doing....
when you feel confident enough, and after reading multiple books and doing a lot of labs, get a job in Linux administration...get at least one year experience, then start worrying about certs
i agree with jnw,
i see that you have years of tech support - so go ahead with linux+ (1 exam required) or the LPI (2 exams).
just learn the material well (not neccesarily those certification specific material, but learning the other wont hurt and also helps you a lot) - inside-out, do the labs, and good luck with job hunting
cheers!!!
