VGA to HDMI adapter?

I have an older InFocus X-1 projector which still works really well.  Just wondering if I should give up on trying to keep it relevant.  Being that it only has VGA, S-video and composite possibilities, I need to see if I can find a VGA to HDMI converter that actually works or just accept that it is old and I should buy a newer projector with HDMI.  Appreciate your suggestions.
