I ordered one too after seeing your pictures. It seems like the Amazon price is not exactly deterministic-- I got mine for $11.90 yesterday and the same link today shows it at $14.48. Perhaps these are commodity priced, you know like corn :-) I will try mine with various DEC terminals, Heathkit H19/H89 and several other composite monochrome sources. Your 80 column display looked really nice. I had similar results with a GBS-82xx converter driving into a VGA LCD but I would say the text is not as crisp there likely due to the additional conversion back to analog VGA which your solution would eliminate.
