Please don't take my words as bashing Carters, I may come off that way. I love the work he does, and I have enjoyed every Carter I have owned (even the annoying banana trigger one), but it is hard to beat Phantoms (they are the most refined a Nelson can be, in my opinion).
That is not to say that Carters don't have amazing fit/finish and build quality, they really do, but you pay a premium for that. Try to get your Phantom working, but look into a Mini-Comp anyways, because Carters are awesome. Just don't buy it thinking it will shoot circles around your Phantom.
