La Perla II here...
I have the La Perla II. I purchased mine 2 two months ago and it is a fabulous machine. By far the nicest dishwasher I've ever owned or used. The racks do take a little getting used to. But, the more I use this machine the more I find I can load into it. It is very quiet and cleans very, very well. I had mine hooked up to cold water as I have a lot of fine china that was my grandmothers and felt better knowing the machine would heat the water to precisely the right temperature itself ( 115 degrees F on the China & Crystal cycle ). I find that this machine takes no longer to complete a cycle than the Kenmore Elite that it replaced. Mike is right, the Pots & Pans cycle packs fierce wallop of high pressure and high temperature. No dirt survives. My flatware gleams when I take it out as does my stainless steel pots and pans. I highly recommend this dishwasher to anyone. If you entertain a lot, this dishwasher is great. It can hold a lot of dishes at once.
When I have my dinner parties, I fill the machine up all day with my prep dishes. Just before people start to arrive, I start up the machine and let them wash while we are eating. Then after everyone leaves, I unload and put in the dinner dishes. In the past with my other machines, I would sometimes have to run the dishwasher twice before my guests arrived and generally twice afterwards. I hope this information helps. Any questions please let me know.
