Buying a new bass advice

[david sumners]

Hi all, great forum here. I'm a newbie upright player and need some advice. I want to get an inexpensive bass to play rockabilly. I've narrowed the choices down to a Shen SB 80 or a Thompson RM 100. Any thoughts ?

PS. anyone know about T.G. Pfretzschner basses ? There's one for sale locally for about $2K. Is it German or a Chinese with a fake label ?

Thx
