Shemale club is certainly a good choice, and they offer a good value for my money.
Speaking of Asian shemales I would dare to recommend
Ladyboy-69, it's an old site and they're working their asses out to keep their members happy. Tons of content, from first-timers to all time favourite ladyboy stars, such as Amy, Mint, Areeya, Lee and others. You can browse the threads at this forum to see some of their pics posted by me and other members.
Plus, they recently started offering bonuses for members who stay with them for more than 30 days (this included their extreme LB fetish site, CD site and shemale toon one). I'm pretty satisfied with what they deliver, and
suggest you give it a try it too.
