I was lucky and found a VGA box that let me switch between it and S-Video/Composite at a GoodWill, back before they went insane with prices, for about $3.
EDIT: I would recommend not using it on a Large TV. It's great on a smaller monitor, but on a large TV it gets really jagged and the less quality of S-Video/Composite really looks better when scaled up.
EDIT 2: But thats just my opinion
