Cogent Reviews?

Hi, all. I'm looking to start a non-profit community colocation facility in Silicon Valley, and it seemed to me that Cogent Communications had the best deal on getting a big chunk of bandwidth ($1000/months for 100mbps). Are there comparable deals out there, or is Cogent the only one at this price point? Do they have good peering? What kind of latency/throughput does one get over their network? Do they have any customers? Any of you use Cogent? Thanks *so* much for any of your input; we're hoping to keep costs way down, any input on this would be much appreciated. Yours, -david
