Who has had good experiences with the Brawler series of carburetors?

It looks like Quick Fuel carries the Brawler line of carburetors. I'm just so shocked at how expensive some of the fancier carburetors have become.
That's why I like the Quick Fuel. They have all of the tuning capabilities of the more expensive carburetors at a fraction of the cost. I think they call those the Die Cast Series.
