I just bought a Yongnuo MC-36 (yeah I hadn't heard of them either) and got to play with it last night, have to say it did well.
It has a LCD display and allows you to set the amount of exposures, length of exposure, interval between exposures etc, it even has a backlight which is handy when your out in the dark. Build quality seems pretty good, if anything I noticed that It would come out of the socket pretty easy but that didn't cause me any concerns.
I paid £38 from Amazon, which is a lot less than the Canon version.
