Used Romanians in the market place..

[Eduardo Barbosa]

I got one of these Romanian basses. flat back, slightly larger body than a 3/4, some people call it 7/8's but the string length it's between 41,5" to 42'.
I paid $2600 new. I needed fingerboard dressing, and little bit of bridge re-shaping.
i sold for $2000 after a few years for no particular reason other than I have two other basses, and I just didn't need a third one.
what does puzzle me, is that I think I have seen this exact same bass on various web sites with different labels.
So now, if indeed they are the same bass, which in the back of my mind something tells me they are. I can't understand why the price tags vary from about $2400 to $12.000!!!!!!
I suppose that if you get them blank and have to varnish and set up, that would add up too the price tag.
But an almost 10k increase???
I have asked a couple of luthiers about it, but they where vague about it...
Anyway, i've seen them selling used from about $1800 all the way up to $12.000!!! (yes! used, but with reputable shop label...)
