That's maybe 10 times the price of OP's 'old hybrid'.

That site disparages other kinds of "tamper-resistant" bolts, but perhaps these are easier to find and would seem to offer a good measure of security against casual thieves. such as: http://www.tamperproof.com/

What I really want is a seat post with a locking clamp that can't be opened (to remove the saddle) without a key. Does this exist?

Lots of people have the bike chain inside inner tube solution here in the Bay Area... but is a bike chain really harder to cut through than a cable? And can't someone with a chain tool just unlock the chain? That probably would take under a minute for a thief with some practice (given that it's such a common method around here).
