are there any supersonic dog training devices that work from more than 20 feet away?

If so send a link. If you dont know, dont waste my time and dont answer.

I do think you mean ultrasonic. Unlike the snot that answered before me, here is a link to some different ones on amazon:

Dog Training Device

Is there a time.....?

Everyone has different views on what kind of training methods (collars/harnesses in particular) to use. As far as collars go (prongs, chokes, electrics, etc.) is there a time when it's okay to stop using the device, and switch to a regular (flat) collar?

I've heard arguments for both sides. My parents (not the *best* dog owners in the world) are avid choke chain users and cannot understand me switching two of our dogs to flat collars and one to a martingale (she has a large neck and tiny head) rather than use chokes their whole lives. All three dogs walk wonderfully on leashes.

Personally, I think once your dog is trained to walk well on a leash, the training device shouldn't be needed anymore. However, it wouldnt be the first time I am wrong about something . I *am* still learning.

What's right?

Once your dog is trustworthy, it is absolutely okay to switch from the training collar to a flat collar, in fact, that's why it's called a TRAINING collar because it is to be used for training purposes, not necessarily every day use.
However, in my case, I have very large, powerful dogs and I often walk 2-3 at a time, so when I am walking more than one, just to make sure I don't ever lose control I will have them all on a prong collar even though they don't really need it. I would just rather be safe than sorry.
It's really up to the owner and what the owner feels good about. If you trust your dogs on a flat collar and feel that you can keep them under control, then fine. There's nothing wrong with that at all, and in actuality, that is the ultimate goal.
