Angus you can also have a look at the Smartfly products, i have been using their PowerExpander Pro in my SM F-86.

Their PowerExpander Eq10 has a lot of the same features as the powerbox at less than 1/2 the cost.

I believe it has more features, you can adjust all 10 channels.
As for the 42% board, the only thing that has me worried is the lack of heat sinks for the voltage regulators. Unless they were removed for the picture. I have not heard of any pine swingers using this board yet.
