SuperKraft has made a pretty good name for them self. My experiance as well as this forum seems to confirm that their models are excellent flyers, well built, and quite a value for the price. Ive have both the .60 CAP232 and the .40 Extra 300 and my only complaint was the hardware sucked on the CAP ( a VERY early kit) and was second rate on the Extra ( a year newer but still 1.5 years old now). To me the hardware was of little importance.. but more recent mentions here indicates they have improve the quality to the point where most people are happy with it. One thing for sure, their customer service is first rate and since Im in Maryland and they are in New Jersey, I get quick service too.
FWIW, Id go with the Extra.. the CAP is a typical CAP and is snap happy... the .40 Exra size I have is actually TOO stable,, cant get a decent snap roll out of it. I consider the .40 size to be SuperKrafts poorest effort as its rather slab sided, while the .60 size has a VERY nice shape(I wish I had bought it instead of the CAP which I DID snap into the ground). But a friend talked me into dropping back to .40 size....
Bottom line: buy a Kangke... you wont be sorry
