I don't think the Sanwa is much different in price to Universe when it was released - and the Sanwa is dedicated 2.4...
Personally I am also using the new FHSS module and receivers with my Universe and it has been faultless every time with a very fast bind even indoors (where the old module struggled for me).
I think the Sanwa with the bonus receiver deal when it is around (was last week) is great, and if I had to buy a new radio it would probably be that one - but I do prefer the dimensions in hand of the KO
I'm hope i'm wrong but I really doubt we'll see a new stick radio from KO, the market just isn't big enough for them
