The Prodigy is a great little spa. It is not an overpowering spa, but does have plenty of power. It is from Hot Spring, so that is a big plus. Hot Spring is known to be a quality company.
From what I understand (my dealer is also a friend) the Prodigy continues to be a great selling spa. Its been around for awhile, so if it is still a good seller, that tells you folks really like it. I have found it to be very comfortable to sit in as well.
The biggest con is that it does not have a Moto Massage. If you don't consider that jet a must have, then the Prodigy is a great choice.
Have you wet tested it? That is certainly something to consider. If you have any specific questions, feel free to post them or PM me.
