Just want to throw another option in to the mix. Personally I think the difference between the higher priced boards like the DNA200 and the SX350/450J boards has narrowed allot in the past year. However they do work flawlessly and give instant power and are highly customizable. Watch Pbusardo's latest video explains the customizations you can do. Well worth the watch if your on the fence it might push you one way or the other and you only need to watch the escribe bit as thats the one for the DNA75/200 boards -
The other option anyway is the Hcigar VT133, a really nice DNA200 mod running at 133, I say this because gearbest has them on sale at the moment for £70 - http://www.gearbest.com/temperature-control-mods/pp_335135.html but I reccomend the rubberised battery door for them, they fit really snug because they are rubberised and feel really nice in the hand - http://www.gearbest.com/temperature-control-mods/pp_348521.html
I personally preffere my DNA and SX mods to my cuboid which is a similar chip to the RX200 but I use temp control and feel the DNA and SX do this the best.
