That slide out GE was the exact one (in pink) that my parent's wealthy friends had in their gorgeous big house back in the late 60s.  Which must mean it was already a few years old by then.  I remember climbing on a chair and reaching in when I was less than 5 years old!  We never had and never would have deluxe appliances like that until I had the money to buy them myself.

I absolutely can see the difference in quality of vintage dishwashers in larger, more solid parts, and interestingly their technology was not that far behind current offerings at all.  In fact if you read the vintage GE description it suggests a prior version of the new GE's feature of a built-in semblance of a garbage disposal that mitigates clogged drain lines and filters which cause lowering water pressure and efficacy.

I'm getting a new portable dishwasher replacing a countertop dishwasher that wore out in just 3 years use.  I chose the GE featured in the link I attached, not because of brand alone, but because none of the other portable dishwashers that I researched had such modern styling nor the 3 main features listed that I was impressed by.  Check out the link for those. 

The vintage GE Tom showed even featured forced hot air drying, which is even considered a luxury dishwasher feature today and is hard to come by.

So, since no, and I mean zero, vintage portable dishwashers were available on line or in a cool vintage appliance store in San Fernando valley I visited, I needed to go with new, but feel I found the best one of the competition today.
