I do.
I'm not particularly fond of gravure videos though, I like photobooks instead.
A lot of the gravure idols that I started out with are no longer in the business. They got older and either moved onto mainstream modelling (e.g. Haruka Ogawa), or got pregnant and married and disappeared from the limelight (e.g. Miho Yoshioka), or just completely vanished without a trace (e.g. Aki Kawamura).
The ones that I'm really fond of who are still more or less in the business are Sayaka Isoyama and Yoko Kumada.
Ai Shinozaki is really growing up to be very fine though, when she started out she was way too young for my taste.
edit: Also, the maintream gravure scene has changed a lot from when I first got into it, it used to be mostly fairly tame swimsuit photoshoots, but now everyone has to toe the idea of nudity. In addition idols who are openly very risque (e.g. Dan Mitsu) are more commonly accepted. Such idols used to be restricted to the nude-but-not-porn gravure scene.
