Are you looking for a DIY kit, or a ready to fly kit. Also how much you want to spend?
I have looked at the 210 FPV Vtail quad from eachine, and for the money it is decent, but it is definately on the lower end of scale. But for the money its hard to beat! Also just because its RTF you will also need to configure the FC to get it flying very well as most eachine quads are not setup out of the box very well.
