I know the title says "Hofner Alternative", but have you considered the Hofner Ignition Club? 30" with (IME) better ergonomics than the Violin. The Ignition are fully hollow like the German models (the HCT are semi-hollow, with a solid centre-block), and should come in close to the $400 budget. I bought mine with no expectations of having it as anything but 'wall art'; after a few hours on the bench and a new set of LaBella black tapes it sounds great and plays great so gets a healthy share of genuine play-time.
Regarding intonation, it is worth bearing in mind that a low action with minimal relief, a well-cut nut and properly-set witness points reduces the compensation required at the bridge. It is possible to get very close with the Hofner bridge once all other setup elements are addressed...
