I did expect to keep the TT (Clearaudio Concept) for a few years. I hope getting the Coincident will not make do that upgrade too.
Based on a quick read-through of this thread, it seems to me that this is the major issue that needs to be considered. As Banquo mentioned earlier, the Coincident phono stage will not work properly with your present cartridge. In addition to the gain issue he mentioned, it does not provide suitable loading for MM's. So you'll want to invest in a high quality LOMC, that will do justice to the phono stage, and not require further upgrading in the foreseeable future. And although I'm not familiar with the Concept, I'd seriously question whether a $1400 turntable + tonearm would do justice to that cartridge, if used as anything more than a temporary stopgap.
I don't mean to be discouraging, but I'm just suggesting that if you go for the Coincident you should be prepared for the possibility that you'll want to upgrade the turntable and tonearm sooner rather than later. And seconding Isochronism's point about buying once, that upgrade, done right, is likely to involve considerable $.
