that is a great deal on the xp10s. for mixing, beatmatching, i would take 2 xp10s and a traditional mixer over the RMX and probably even over the vci-100. you could use the bison software that comes with the xp10s or really whatever software you like, traktor, deckadance, etc.
i have an xp-5 and i love the jogwheel and the extra long pitch fader, works great for beatmatching.
