More playbacks

So my dilemma, as well as others I'm sure, is that I need 10 more faders. I really don't want to spend another $6K to get a playback wing, the hog 3 USB wing is in such high demand it's almost impossible to find and if you do find one the price has been inflated so much because they know it's best alternative and high end is the worst about playing well with others and allowing devices to be connected or dmx pass through. What's a guy to do??? I can't be the only person ready to pull my hair out over the lack of compatibility with other systems. I get it, you want people to buy your products. The problem is I'm becoming less and less turned on with hog as others like GMA work to interface with other things. What can I do to rectify my situation without breaking the bank?

While I'm at it, I really think it's pretty ridiculous to not allow Hog PC to use encoders from an iPad with touch OSC. Why high end? Why?
