Murray carbs?

What yall think about murray carbs? Spendy but maybe worth it if they work the way they say they do.
 

They are somewhat unique and would be a worthy addition if you were building a hardtail, so something along those lines.  In terms of more mainstream usage, they seem spendy compared to rebuilding a set of stock carbs.  And one nice thing about stock, you don't need to fart around with jetting.

This topic has come up many times and my view remains the same (it is only my opinion) auto manufacturers siamees carbs for reduced maintenance and better gas mileage (a compromise) but every engine tuner since the 50's has, where the rules allow favoured one venturi per cylinder (carb or throttle body) this allows for a shorter intake runner and a straighter path into head for the intake charge.
With regards to "their claims" - according to advertised claims, an exhaust, jet kit and K&N filter will make my "K" faster than an injected GPZ1100 (they all claim 10 - 15 percent power increase for their products) so I don't know why the factory bothered designing a new head & cams etc. Take Nessism's advice, save money and go faster
