Older Melco??????

I have an opportunity to purchase 3 Melco EMC 10 's(circa 1996-1997?) and am wondering if anyone has any input on these models in particular, or what my risks are with going with an older machine. Basically it is economically a good deal for me, I just want to make sure Im not going to shoot myself in the foot. I have never done embroidery in house.

Thanks
