Okay:
1) How many analogs there are on a controller shouldn't be the sole source of its selection--the largest consideration should be ease of the conversion to 15 pin.
2) Unless they changed it, there's still that $100 electronics limit that still applies to controls. Keep that in mind if I'm right on that one.
3) Just use a controller designed for 15 pins. My
Axis Pad has served me quite well, and should address all of your control issues.
