Hex editor control for Windows Forms?

There is an old project I'd like to resurrect, and always wanted to add some hex view to it. These are my main needs:

• Easily used in .Net Windows Forms, preferable if it is written in .Net itself.
• Reliable and with a somewhat decent look and feel, nothing fancy, I just expect it to always work as expected from a hex editor, not jumping from the hex columns to its ANSI representation, and that sort of thing.
• Allows to edit values.
• Fast, although the amount of bytes loaded is gonna always be rather small.
• A license as unrestricted as possible. I'm gonna freely distribute the application and its source, which is often not a problem, however I don't want the control to impose me some unwanted license.

I've seen several open source .Net hex editors out there in my lifetime, however, since I've never really needed one, I don't recall all of them nor know which one to choose.

I've had good success with HexBox: http://sourceforge.net/projects/hexbox/
