The matchbox should work. The Hitec programmer is a good tool also, but you will need Hitec digital servos that can be programmed. I don't think your analog servos will work with it. The last choice would be a reverse Y or changing brands on one servo. I did not have good luck with either of the two reverse Ys i used in the past, hence my hesitation. Futaba servos run the oposite way of Hitec servos. So while it may be hard to find two that match up it is possible to run one of each brand on a normal Y and do what you want.
BTW these suggestions are listed with the best option first and poorest option last :-)
