The 16/15/2 and 3 are there most popular motors and they have lots of dealers in the US that will have those in stock
NSP are a shop I trust and they have them at $105
but while I like to support the designers not cloners, the HET edf-2w and 3w are only $50 and though i do have a whole bunch of mega motors of all sizes including the 16/15/2 and 3, nowdays money is tight and I buy HET if the size and KV I'm after is available.
The 39mm typhoon motors were the first Nue clones to come out and I hear there USofA made not Chinese, but I dont have any of the larger HETs to tell you what there like.
