I use an old beat up Wacom Cintiq 21UX I got off Cragslist for 200$. It sometimes doesn't turn on. That's always scary! (It may not look like much, but it's got it where it counts)
I also just got a "New" five year old Wacom Companion. It's my backup and portable workstation.
I use Photoshop CS6 to sketch, pencil and ink and letter my comics. I know Manga Studio Pro would probably be more suited to my black and white art style, but I know photoshop shortcuts.
Sometimes I use a plain old sketchbook and pencil to sketch out sequences of pages. That helps a lot.
I upload to a wordpress website using Comic Easel theme. As well as Tapas!
