I remember those. I used to work for B&D. They were good on very thin material. I'm sure they are obsolete as they were not a big seller.
They still make power shears including ones that attach to the front of a drill but I have not seen the two roller type you are referring to in a long time

Black & Decker discontinued the shear.
A company called P&P Power Inc. of Kincheloe, Michigan, apparently liked the tool enough that they're making a clone which P&P calls the "the VING (Versatile Innovative Non-Galling) Cutter"
P & P claims the tool is capable of cutting 20 gauge flat metal roofing and 24 gauge ribbed metal roofing. According to their website the tool currently costs $395.

The Black & Decker version sometimes shows up on Ebay. The Black & Decker were model number
7975. I haven't checked past auctions, but supposedly they sell for between $100 and $200 or so.
