advice required on double needle machine

[RQR]

Hello all I've been looking out for a double needle, narrow gauge machine for a while and what do you know one pops up out of the blue in the local ads!
It's a sunstar, needle feed machine, missing one of the hook plates but apparently in good nick. I know nothing about this brand, is it in anyway reliable? Can parts be had? Even though it's cheap (350€) I'm wary of a false economy.

 

Thanks in advance!
