I didn't see this mentioned. The right joystick self centers. The left joystick centers from left to right, but "clicks" up and down. This allows you to set the throttle.

As for next electrics, there are a group of electrics which they consider "aileron trainers". This is mostly since most electric pilots start without ailerons and many move up to ailerons. In gas, you are more likely to start out (with an instructor) and with a plane with ailerons.

Two that seem to fit this bill are the Switchback (Mountain Models) and the Grumbler (don't remember the manufacturer).

I've seen reviews on both, but haven't actually flown them.
