I want to install a small garden window. I'm seeking one that has a
clear roof, good insulation on all sides, is well built, and allows
enough light through to grow seedlings and plants.

I found a Pella that looked good, but they claim they don't market them
in this area. I want to avoid one of the dealers that hawks them on TV,
then sends a salesman who doesn't know the details of the product to
close the sale. Plastic is OK, but I want wood on the interior
(finishing it myself is no problem).

Please name any manufacturer who makes a good garden window.
