A+ certified... now what?

Hey all, first post here. I just passed my OS exam (2003 objectives) on Wednesday with a 772 and am now A+ certified. I'm trying to decide what cert to go for next. I'm thinking either Network+ or maybe a Microsoft cert (MCDST?).
I started out 10 years ago doing dial-up tech support for a local ISP and as the company kept getting bought out migrated through several different jobs including cable TV installer, cable modem specialist, and now back to IT as a desktop tech/jack of all trades.
I've got a little experience with lots of different IT niches, but I lack a solid background in any one.
Any advise is appreciated.
