I have a Simac Il Gelataio 1600 like the one I found on eBay linked below. I've owned a few different machines over the years and am happy with the Simac despite two cons.

1. The unit is very heavy. Combined with its size, it's awkward to move around. I don't have a spot large enough in my kitchen to dedicate just to the Simac so I can't store it on my counter. When I use it, it needs to be moved out of, and then back into, the garage.

2. The bowl isn't removable for cleaning. Some Simac models do have a removable bowl.

On the positive side, the thing is built like a tank. I can imagine it lasting for many more years to come. Ice cream comes out great every time, and it's incredibly easy to use.
