What Cert should I go after next?

I am a Desktop Support Technician with 4 years of experience. I am A+ and Network+ certified. I'm thinking of moving away from CompTIA's certs since you now have to renew them every 3 years, and for a CompTIA certs I don't think that is worth the effort or money since they are consider entry level certs. I'm thinking of going after MS MCTS Windows 7 configuring 70-680 exam. Is that a good idea or should I be going after a different MS certification first?
Thanks

So before you start going after certs you should figure out where you are and what you want to achieve through certification. For example, if your company were looking to roll out an upgrade to Win 7 then both the MCITP EDA7 and EDST7 would be good choices to place you in a lead position in that project.
