Whatever you do when the time comes, take your dishes to the store to fit them in. I harp on this, but there's nothing more irritating than having things not fit.
I've got a 10-year old 100 series Bosch in Detroit, it fits Corelle beautifully---but is less happy with thicker crockery. Holds LOTS of Corelle--even bowls nest in beautifully--just love it. Use fairly thick-handled cutlery which fits in the grid standing up nicely. There is a good stair-stepping of the cutlery basket which exposes everything.
Have an 800 series in California--we use Fiesta Ware out here and it's happy with the thicker crockery due to tine placement, but I'm not sold on the 3rd rack for flatware (though haven't tried the thin-handled cutlery in the bottom-rack-silverware-basket, so I might not hate the 3rd rack too much).
TBH notice the cleaning performance isn't much different (though the hard California water makes the dishwasher door look a bit mottled/streaky). The water in California is a little more finicky about needing higher-end detergent, though.
