The composite looks good enough for me.  My video card can capture that too.
But I don't mind paying for quality.  This is important.  Do you have
anything you want to publish?  Or are you planning on building them and
selling them?  I'd like two of them right away.  :-)

I've got a Commodore 1802, and an Amiga 1080.  And you're right, I can see
the vertical bars a little bit, but on the monitors I liked it because it
made the pixels look crisp.  It wasn't annoying.  On my video capture card,
the vertical lines are much worse and they are annoying.
