Yo tkernus,
The Murph's Cruise Control is the BEST. It is the same as the discontinued Audiovox CCS-100 that has been in use for years. Almost bulletproof and very reliable, the CCS-100 has been adapted to lots of vehicles including HUNDREDS of Connies. The install is straightforward and anyone who can adjust their own valves can get through it in a weekend or less. If you're not too far from me (I'm in El Campo, Texas) I'd be happy to help with the install sometime. The kit is about $170 from Murph and is the single best thing I've ever done to my bike to make it comfortable and less fatiguing out on the road. The cruise and a set of highway pegs and a decent seat and as long as I have gas money, I can go.

THis addition will save your wrist, hands, arms, shoulders, back, etc. It allows you to switch hands, use no hands (if you're like me), change position, lean back, and simply relax a bit when on open road. I've also used it a LOT just riding in any stretch that I want to keep my speed in check and there isn;t too much traffic. It DOES shut off when hitting the brakes or the clutch, so it has those safety features that a throttle lock does not (though they are usually easily over-ridden). The kit comes WITH a vacuum cannister that also helps the bike operate smoothly up and down hills while keeping your speed where you set it. If you can't tell, I LOVE IT!
