The Saga SS 10-P is a contender, available from Elderly Instruments for a modest $325, but the neck is a short scale, for open C tuning. That was my first thought as well, but then I got distracted by what else had been developed for this niche market.
I am somewhat concerned about the "exotic wood issue" at border crossings. I don't know how real this issue is in practice but I'd rather not run the risk of losing one of my vintage Stewart banjos.
