I've been looking in to multi-channel radios too lately and have narrowed it down to the following:

The DX18 as Lil Giants sugested

The DX10t although the sticks seem to close together but you can change switch modules for different configurations

Then I stumbled across the Graupner range of tray style radios, the MC-16, MC-20 and the big daddy the MC-32.
These are upgradable with extra switches and you can bind multiple receivers for extra channels, not sure if they are available in the states but I guess you could order from europe?

I still haven't decided but am leaning towards an MC-16 which is 8 channel out of the box and upgradable to 12 channels later on (more if you have multiple receivers)
