Cups look great too mate... [smiley=thumbsup.gif]
Dont know if Im trying to teach you how to suck eggs, so please ignore if this isnt appropriate. ::)
Ive found that sitting the cups direct on top of the polished s/s cover(s) soon starts to scratch that wonderful mirror finish and mars what would otherwise be, a pristine and new appearing machine. We had some of those rubber "grip" things that assist with removing tight jar lids, so just cut these to a slightly larger diameter than the cups and sat these on top of the machine, and the cups on these.
Stops all signs of scratching and since the rubber is full of holes, the cups are still warmed up quite satisfactorily. One thing I noticed though, over time, is the tendency for the pattern of the rubber "coasters" to leave a slight impression on the s/s finish. This just rubs off though, with a microfibre cloth and the finish is returned to its original lustrous polish. 8-)
