Let's say there is a "dead" CPP2, which just can't be used without a total overhaul. Then I'd say, if everything can be contained w/in $600 would be around the threshold for me, including shipping. For a complete ressurrection, that's not expensive.
BUT, considering how shipping would be prohibitive between Croatia and, say, the US, I think a DIY kit & tutorial video for, say, $350 might be a coold option.
I personally have stashed away a late version CPA2 just in case my CPP2 dies so I won't be needing something like this for a while (fingers crossed).
On a completely unrelated note, no word on the camera yet
