If you live in Utah and don't have a soft water system get one of their models that has a built in soft water treatment system. You can buy the salt off of Amazon. Your dishes come out looking new and the machine is super quiet. I found a good deal on one of their lower models at Lowe's. They were running some deal to get it installed for free plus there was a Bosch rebate. I think I paid just over $400 for it (after the rebate). Their top models are awesome but you'd be paying $1k for them.
