Jeff, I had a Montane Litespeed but after seeing how my wife's Houdini performed in the same conditions picked up the Houdini. After wearing it for a few weeks I sold my Montane. I have a review posted on BPL.
The Montane is a good wind shirt, but the Houdini is superior. I'm sure if you look you'll find a Houdini from some supplier, or, if you can wait a bit, Patagonia has a big outlet and store sale around President's Day weekend in February, where you are likely to find one. Also, Patagonia may carry a new Houdini in the spring, and with the current economy, you're likely to find more frequent and deeper sales.
That jacket is one of my favorite and most used pieces of gear.
To those Montane fans out there, the Litespeed is a good jacket and I'm not trying to make fun of your gear, only share my experience with it.
