I have a clone that I have yet to make me do the happy dance. I rather suspect it's me, but I think there are plenty of lovely RTAs out there besides the Prime. To be fair, I have not put the work in to make it "shine" but I like the doggy style (you can really only get clones, due to availability of the original) the nature true tank, and a bunch of others.
Doggy and True are great for flavor.

Get a clone first is good advice in my opinion. My clone is well made and seems pretty darn similar to an original. I'm glad I got a clone, I have yet to find a Kayfun I really enjoy.
