Oh, what a choice to make.... LOL Thanks to everyone for their input! It can be difficult to be objective about a machine sometimes when one is smitten by it's looks....
IF and say this is still IF, we get the house we're currently looking at, we're going to have to 'correct' a space left by a commercial-size refrigerator/freezer unit in the kitchen. That space will easily accommodate a refrigerator (still have to pick THAT, too...LOL) and a portable dishwasher of some description. So, if the range winds up being the Flair, the refrigerator the '65 Frigidaire Cycla-Matic, then the built-in dishwasher will probably be the Spin-Tube. The portable would then have to be the KDS54, kept portable, but repainted turquoise.
No second kitchen in this particular house, though. It has something MUCH bigger and better but I don't want to jinx anything....
I'll be sure to post about how this winds up playing out, I promise.
