Transe-Generation- A bit of "laughter is the best medicine", Transe-Generation- drawn and written by Matt Niishi- finds the humor in everyday situations.
Venus Envy- Quite possibly the best Trans-themed comic on the web. As well, it's one of the few I've read that has a FtM character with a fairly major role.
