I think you have answered your own question. Sounds like you feel the same way as I do about High Speed....meh.

If you don't enjoy the game and don't plan on keeping it, then you are right ~ it will be a big expenditure of both time and money for little return ( read $1.50 per hour ) . With the new pf coming out, no one will want a mediocre machine. I'd say you stand to make the most $$/hour by simply getting the machine working 100% and then sell it to someone who plans on doing a pf swap.

You could try a re-theme on it, but that only works if you like the game play but hate the theme. Personally, I'm not a big fan of either, but the gameplay is the weaker of the two.
