Looking for an SMS type textbox control

Hi guys,
I'm looking for an SMS type vb textbox / textarea control for a vb windows forms application.
Essentially, its a chat window I'm creating, and I want to right-align messages that I have typed and left align messages typed by others (or system messages).
Needs to be scrollable so I can add line after line.
Even better if I can format them differently - different colours etc - line by line.
