Hi,
I use a fairly old ATI All-in-Wonder 8mb PCI card. But, I don't output to a TV, I decided to use a 20" monitor I found on ebay for $150. I'm still using the AiW because everything appears perfectly on the screen in mame and nesticle, and I can use the coax input to double the arcade machine as a tv when i'm not playing. I paid probably over a hundred dollars for the card back when it first came out. Now you can get it for peanuts.
