If anyone knows differently and can point me to a showroom, I'd be
delighted to check them out. I'd love to discover I have options for
a decent aluminum-clad wood slider other than Marvin, since Marvins are
very dear, but I have to be able to hold the competitor in my hands. I
won't drop $20K installing a product in my house sight unseen.

Why only aluminum clad? The Andersen vinyl clad glider is a very nice
window. Very tight.
