I am thinking about buying a used Adler 105-25 MO from another member here. I know very little about this machine and I was wondering if anyone could give me some advice. I just need to know what the advantages or disadvantages are. I know the Adler machines are high quality..just need info about this model. I have researched it online but can't find much about it. I will be doing saddle work and maybe some straps and tack with the machine. Any help would be greatly appreciated.
