Any recommendation for a steel, quality made moka pot that makes 1 liter or more of coffee?

I already own the large Bialleti. It makes ~1 liter of stovetop espresso coffee.
The problems w/ it are:
a) It's aluminum (yuk)
b) Cheap manufacture.

I also own the large Giannina. It's wonderful. Steel, high quality manufacture. It makes better coffee than the Bialleti imho. But it's too small! Only .4 Liter
