I can't believe you shower with your bird. That's fantastic!!! I shower occassionally with Bailey and he LOVES it. It's such an inspiring bonding experience and it really speeds up the training process.

I think a Green-Cheeked Conures are going to be the best bet here. They're about the same size as a Sun/Jenday Conure and their colors are just as beautiful in real life. Plus, their screams are more tolerable and they're comparable to cockatiels. Good Luck! They're fairly inexpensive, too.
