F14 is awesome. I don't like FT myself. Value wise, I would say the the two plus $300-$400, depending on condition.
Don't get too put off by the maintenance of your sttng.
As for the trade, it obviously appeals to your, regardless of what others might offer opinions on.
If you are not in the position to buy another, I would say do it solely in having two machines will keep you more interested than just one.
