Fuel Pump Options

I know I've posteds before about fuel pumps and I'm seriously ready to it the buy button on something. I wanted to ask about other options though. Does anybody have experience using fuel pumps other than Walbro? I've read about Denso RX7 TT pumps and Supra pumps. RRE has some good information but is the installation just as easy as the Walbro? Is there a pump that flows a little more than the 190 but doesn't require a regulator like the 255? It seems like there should be something there. Thanks.
