Thanks for the reply.

From my impromptu internet research:

I've found four buckle systems, two street, two track.
The track systems are either 5 or 6 point using either cam-lock or a 'stack and latch' deal of thick folded steel. The cam lock is much spendier, the other is not really refined, but might be OK.
The street systems I've seen have either a push button release or lift to release (like on an airplane) type buckles.
There are four point street systems that look appropriate, and use 2" belts which would probably meet my needs, I'm guessing that 3" webbing might be uncomfortable. Momo has one, racer's choice has one.
It seems that the five point is kind of an entry level race system and you can use it without the anti-submarine strap. True, it is probably overkill, and any skirted passengers might not appreciate it.

Just wondering what these things are like to live with, and beyond the obvious, what installation wrinkles might exist....
