Melco 4 head machine

I am considering purchasing a 1993 Melco 4 head machine from a private owner. I am only familiar with Brother machines. Anyone have any advice? I know it is an older machine that is not supported by Melco. I am interested in hearing from anyone that is currently running a machine like this one.

I'm looking this day's to buy a Brother BE 1204 BC, but only after check the tech support and spare parts shop!
