I am a diehard ASL fan, so naturally, I would suggest a top line Hill style bow. They are beautiful and very nice but can be costly when purchased new. However, you can find really nice items in the used market at reasonable prices. There are Trad Gang sponsors that carry them as well as the member classified section if you are a contributing member. The main reason I suggest a top line bow (used) is that if you don't like it in the long run, you can get more of your money back out of it than with a lesser bow.
In addition, a number of fans of R/D or other styles will give some good recommendations as well, so whatever style you select you will find good info on them. It has been a while since I shot R/D, but I have a Deathwish by Steve Welte (I think his daughter now builds them) that is a very good bow. I also have 3 Dan Quillian Bamboo Longhunter bows that I consider to be a very underrated bow. Unfortunately, you don't see them around much unless you seek them out. Its all good, so try as many as you can and buy what strikes your fancy. You and your wife have started on a fascinating journey. Good luck on your quest.
