Check out these mid-controls for the America from Raask:
Raask Mid-controls for The America I emailed Raask and asked the cost. They replied the distributor in the US was "Omar's Cafe". I emailed Omar for a quote. (pretty cool place)
Omar's Cafe/Raask Distributor I'll post what Omar sends me. I'm interested in sitting upright if the cost isn't TOO high. Raask stuff is usually first place but pricey.
