I prefer this design over the one with the dial on the side, I bought one of those off ebay and it didn't work properly, it definitely didn't work as it said it should... buttons were erratic, didn't work some of the time. Eventually sent it back and ended up buying one from a local shop for $160

but it hasn't missed a beat, and gets bashed around quite a bit. For the price you are paying it probably will work pretty well, but don't get too disappointed if it doesn't, it's like a lucky draw with this kind of stuff.
