We have a Magic Chef ice maker that we bought at Home Depot a little over a year ago. It's a nice compact design, a little larger then a bread machine, and can make ice in about 7 minutes. You fill the bottom with water, and it draws it up into the ice maker part. It makes 'dome' ice cubes with a hole on the flat part. You can choose 3 different size cubes. Takes about 7 minutes per cycle. We leave ours plugged in and running all the time (we use a lot of ice in our house, and yes, we have an icemaker in the fridge....we really do use a lot of ice) anyway, it dumps the ice into a catch bin that sits above the water resevoir, it's inuslated, but it is not a freezer compartment, so if it's not used, the ice melts back into the water resevoir, and then it gets refrozen into cubes.
I deffiantely reccomend it if you're looking to increase your ice production without buying bags of ice. Great for parties, as it makes ice quickly. I forget what we paid for it, I think it was around $150 though.
