Seems like an interesting service. I'm kind of confused by the site though.

On the landing page it says, "Get any schematic symbol and PCB footprint delivered in 24 hours. Just $29." Then I did a search for a part and clicked request and, after signing up for an account, it said that to get it in 24 hours I need to pay $79 and $29 was for 5 days service. I also somehow ended up on a page at one point that said that you could request any part for free. So which is it really?

I also found the social network aspect of the site off putting particularly since there was no mention of that and then after I signed up for an account to give the request a part service a try I see my user name plastered on the sites front page in a feed of recently signed up users and deactivating my account doesn't remove that.
