MIT 330 shotguns, how do they compare to the newer

Hi there, Im a big fan of my MIT 330 Shotguns and was curious to see how they do against the newer ones. at only $150-200 a pair their one of the best cables on a budget I have found.

Anyone have experience with them and the newer shotgun series? Also would my better upgrade to get an older pair of 350 CVT's or 350 EVO Shoguns and wait to find a pair for around $1000? or would it be one of those things where Im just taking things too far?
