Chazzlee,
You may have a different aesthetic than I do, but that Velo 5 is rather, uh, let's say...unattractive. I'm sure it's reliable; I've run Cateye Mity 3s for years now without any troubles, but that model, with it's dual buttons and simultaneous depression requirements doesn't meet your standards.
My suggestion is that, if you haven't already, give the Knog "NERD" 9 function a look :

It's one piece/no button...uber-simple. It simply straps on...or off, so if theft is a concern, you should pop-and-pocket it. (Actually, it's two piece; you can pop out the computer from the case to change the mounting orientation, e.g. for stem placement)
It ain't a beauty, I concede, but it ain't ugly, either. I'd call it "funky hip". Mine has been running hassle-free, so I'd say reliable, too.
