If you want custom and R-Tech are out of the picture, speak to Unicorn or Shark.
But, I think I'd personally sway towards APR like Jay says. Yes it's 'generic' but if you were to contact APR and ask them for a comprehensive list of hardware that would best compliment their map, your end result would be as safe and effective as a custom map with hardware xyz. Tweak the hardware to the map, rather than the map to the hardware.
Unless you've already got the usual 2+ parts fitted and APR say those particular parts won't work with their map, I can't see you going too far wrong.
