I once had both the dual joystick and trackball models. Once I got the Tankstick, I didn't use the other ones ever. Still, I held on to them for years. Last year I sold both of them here on AA. I hope the people who bought them love them as much as I did.
You can get new T molding for the edges from Happ/Suzo controls. They also have a ton of awesome arcade controls for more ideas. If the actual melamine surface is messed up, there isn't a way to restore it that I know of, but you can always recover it with other materials (even with custom printing) usually in vinyl.
So far, I haven't worried about an overlay on the "X-Arcade" top, but one day I will cover it... probably with a custom vinyl that I mentioned before.
The ccolest thing now is that with the spinners, I can play 2600 paddle games perfectly with Stella. No more worrying about real jittery paddles

There are tons of other advantages to having spinners for arcade emulation... but I haven't had a chance to explore everything yet.
One thing is that I like is how I setup the control panel with the additions. The spinners are accessible, but not in the way for games that don't use them. The X-Arcade Tankstick is already a "frankenpanel" as stock, and I didn't want to make that worse. If anything, I think my solution may have made it better
