Seen them Combatsim seems to be a place in statis at the moment. I'd really like to see AH banners/ads on Sim HQ.
I do believe the best bang for your dollar is giving out interviews and articles. I'm sure they'd roast me if they could for even recomending this during such a busy schedule but HiTech and Pyro (and the others too!) really should be talking to the e-zines via articles and interviews. Much like we used to see much more fequently during the beta and just after. Of course they just might be too and we don't know it yet.
