V-Brakes for Cross

Hey OBRAland,

I'm thinking I'd like to try V-brakes for cross this fall, so I want to get some mounted up this summer to see if I like them. I run the older generation Shimano 10-speed levers, so my understanding is that I should be using something with an 85mm(ish) arm.

Anyone know of a shop in Portland/Vancouver area that stocks Tektro RX5's?

Or, does anyone have a set of them (or perhaps a set of the TRP CX8.4's for a reasonable price) that they've decided not to use anymore, and want to sell?

Reply off list if you have any answers. Thanks!
Adam
