The ELUs were well built but fetch rather high prices on eBay considering that they haven't been made for something over 20 years. Vendors can say 'good condition' and they may well look clean, but after at least 20 years of use, they are unlikely to be at their best. The 600w ones are probably nearer 30 years old, as the later ones were 900w.
From time to time I look out for cheap ones, with a view to swapping the bearings and carbon brushes, which can give them a new lease of life. There was one advertised on eBay as ELU recently that I'm fairly sure wasn't. The vendor admitted the label was missing, but the MOF96 was widely copied, as the design was good, even if cheaper components were used. I bought a Chinese MOF96 copy new recently for 20 quid with a 3 year guarantee just for occasional use on those occasions when I don't want to be swapping bits back and forth. They aren't ELU quality though.
DeWalt took them over and continued selling them in their house yellow under their own model numbers. The DW625 is the old MOF177 and is a powerful router. I got mine on eBay for UKP150 in very good condition, so you could well do the same.
