10Gb CPE

With the deluge of 10Gb X device recommendations, I thought I'd hit the list with one more. Does anyone out there running 10Gb managed CPE feel like sharing their experiences? Our use case would be a managed endpoint that would allow for testing and circuit verification while providing a layer 2 extension to our edge gear at the PoPs. We're hoping to find a cheap vendor-supplied solution- not homebrew. If so, which features have been important to you? Which vendors have good products? What price point? Thanks, Dan
