Anyone have any experience with garage door openers built for bikes. I came across 2 of them. One is the Built In Garage Door Opener (BIGDO) from these guys http://motofx.com/ it integrates into your signals or light switch, but it costs $75. The other one is a stand alone type from these guys http://mcgdo.com/ and this one only costs $20. I'm leaning towards the $20 opener, just wanted to know if anyone has had any experiences with any of these types of products?
