My mom used to reread the Heyer books in between her rereadings of Jane Austen. Her car actually had a bumper sticker that read "I'd Rather be Reading Jane Austen." This, for her, was the truth. My mother didn't do Regencies, as she thought them a little lowbrow, but she loved Heyer.

My wife likes Regencies and she keeps a database of all the ones she's read - with her comments and ratings. She seems to have an encyclopedic understanding of the whole scene which, sadly, is collapsing as a genre. Very new ones come out each month, a far cry from the large number from various publishers that used to appear on a constant basis. She copes with this decline by tracking down work from the best authors using abebooks. We have to go to a few really crappy used bookstores (there's one in the Haight which is truly a nightmare), just for their dependable offerings of used Regencies. My wife will also buy multiple copies of rare, really well written Regencies if she finds them cheaply, because she's afraid they may be lost if she doesn't. Consequently, we have one huge custom-made bookshelf in our home which is mostly filled with her Regencies.

My wife's biggest complaint are Regencies in which the author has confused the title system. A few minor mistakes won't kill it, but I have seen her throw one across the room when it gets to be too much.
