I've read a lot of people with the MKX have problems with the OSD quitting (which I understand you have to download FW to enable), weak LC filters. For a few bucks more you should consider the OSD Pro board. I should point out though, that the MKX has 2 amp output whereas the OSD Pro only puts out 1 amp. http://www.getfpv.com/quadrevo-powerosd-pro.html
