Go down to radio shack and buy the cheapest mic they have, then try to sell it on craigslist for 2x's what you paid for it. It's new, still in the box..... That should cure you.
Also jones-ing for a new mic, but know that I really don't have the funds for one. Well I do, but really can't until more stable employment can be had. As I continue to widdle away at PVC components to come up with a cheap and more practical tripod / mic stand all in one. That can be partially parted out to convert to a steady cam and other modular funky-ness. I guess it helps keep my mind off the jones-ing part. And it's lighter (and cooler in the sun) than the traditional metal routes. Not really cheaper if you tally up all the parts, but if something breaks, I don't have to buy a complete new one, just swap out the broken part. Available at most hardware stores.
If you must, the KSM-44a has my attention for now. With a newer KSM42 cousin. Not that I care much for the color or style, but the specs seem quite drool-able.
