Take a look at the Holley Sniper. It seems to be a pretty good bang for the buck system.
One engine manufacturer I talked to awhile back had switched their EFI crate engines over to the Sniper system. It's less cost than a port fuel injection system and they claimed there was no noticeable difference when they dyno their engines.
