HI all. Looking to take the plunge to my first Double Bass. I have been borrowing a friend's Becker 6000 (made in Romania) and have the opportunity to buy it. I can't fine much online, two listings from Reverb spanning 10 years and that is it. It feels good, but I have nothing to compare it to. Any idea what it is worth, and if it is a decent instrument or something I should stay away from?

Thanks!
