im tired of watching these 15 sec. clips, are there any great pay shemale websites?

AEBN.com is a good one.  There are hundreds of full length movies.  Its by the minute and you buy time.

If you like your TSes as tops, you need to check out TS Seduction.  Some are bondage shots (boys tied up and used by the TSes), but all feature some of the most beautiful girls I have ever seen.

Try Tranny-VOD - a wide & pretty good selection of TS (and other) video-on-demand (not "Tranny", despite its title) - and you can buy by the minute, etc.  You'll need a fast connection.  Enjoy.
