I like my eggbeaters, even though I got the really cheap ones. Not sure about what you mean with the positioning, it's four sided, so you just put your foot down and it clicks in. Years ago I had straps which were a pain with having to flip it to get your foot in.

Float seems fine, although I am not sure whether mine are set on the 15 or 20 degree side. Either way I wouldn't ride with my foot bent that far out unless I was trying to remove my foot.
