I have heard good things about the Rx Carb (42.5mm mod by Q). I plan to have at least one of my stock carbs Rx'd as soon as Q can do it (get in line and no cutting).
The nice part about using the stock carb is that you don't need a new throttle body or throttle cable. Keep in mind that you may need one or both of these with some of the other offerings. I think the PWK requires a cable and the Lectron may require both.
I have also heard very good things about the Lectron carbs but they are pricey. I know a guy who just got a 48mm Lectron and he loves it. I have my eyes out for a used Lectron but not quite that big.
While I'm waiting for the Rx'd carb or a used Lectron, I may try a PWK, either 39mm or bored to 41.5mm.
