This thread covers a couple of themes. The "refresh" has been properly dealt with.
What concerns me is a request for possible mods without an extensive look into what is currently wrong for the owner. This is almost a guarantee for disaster. Granted, there are players that respond well to "pimping". The horn looks better and all sorts of BS is spread about the improvement.
I think that the owner did the right thing. If they need something different, don't take a chance on a successful horn. Buy something that more closely matches what you think.
