I recently switched from Eggbeaters Candies to Speedplay Frogs on my mountain bike, and I love them. I have always had a little "issue" with clipping in with my second foot (mtb or road, much worse on mtb on bumpy trails) with the Candies. Once clipped in, they were great, but getting in could be a real problem. At times I'd have to ride quite a ways with my right foot out, which doesn't do much for my speed or efficiency!
The Frogs are completely idiot proof, a breeze to get into or out of. I still have Speedplay X2s (road pedals) on my Bike Friday but will probably eventually trade them out for Frogs as well, so I can wear shoes I can walk in. I bought new Pearl Izumi Vagabond (mountain, but look very sleek) shoes for the Frog cleats, and I love them. They're pretty (silver with pale blue), fit true to size, have a nice stiff sole, and are much less pricy than Sidis. I love having the cleat recessed so I can walk in them. Last time I checked, TE carries them. I'd highly recommend the PI Vagabonds -- and Speedplay Frogs -- if you're looking for a mountain shoe/pedal combo that works well.
Good luck!
