Shemales:
TrannyBucks - Just opened up recently so its not totally saturated like most of the shemale stuff. Content is hot and the owners are veterans in the tranny niche so they know how to sell it.
Ladyboys:
IslandDollars - Just rolled out a new lineup of HOT models for ladyboygold and they have an awesome ladyboygf site and a bareback specific site.
GroobyBucks - One ladyboy site (off the top of my head) but they have a network of shemale sites as well.
SpiderDollars - Just opened a new femboy site a few weeks ago in addition to ladyboyplayer. They have shemale sites too.
