Seeedstudio ultrasonic rangefinder

I should clarify my earlier comment when I said I didn't like site layout and that search was generally returning way too much or nothing but it was usable. That was poorly worded. The search is pretty much useless. The site layout, which I don't like much, is usable. You have to go into the categories they set up and for Arduino stuff it means paging through a lot of stuff in an almost random order. It might take 5 minutes to find something that I can find in under 2 elsewhere. But once I found my stuff, they did have good prices and sent it quickly. For an initial large order for a project, paging through the stuff was no big deal. For onesie-twosie stuff it drives me crazy. I did one return - a joystick I hoped would be sturdier - and had no trouble with that. I do tend to use them less than other sites because of the web interface though.
