Well Don, you and I have been down this road before. My point then and my point now is that what is best for you is not necessarily best for me and vice versa. When I had a carb converted by Rupert he knew it was going to be used with an electric pump. He didn't tell me it wouldn't work.
There are several reasons one may choose to not run a belt drive pump. Is an electric any less consistant? Not according to my experience. If cost is not an issue then by all means go buy the most expensive thing out there. I don't operate on a shoestring budget but I feel my car is as consistant as the next guy's.
There is almost always more than one way of doing things and I have always maintained that the best way is the way that works for you.
