i'd say if it seems ok to you and it is working, then spend the money on a monitor if you need one. I'm all for upgrading to better stuff, but you have to prioritize...what is going to make a bigger difference in your gaming experience...an new monitor, or new controls?
i say get the other stuff you want, as long as teh hotrod is working..then when you are happy with the other stuff, get some u360s and make your own panel
