Can't help you with Euromaster, sorry... But, I do have several "original" Westons - I use Weston V on a daily basis.
They're not particularly suited for low light situations (no battery). I think the lowest you can reliably go is about EV 4.
Otherwise, nothing but praise! Once you learn how to use them and where to point, they are very reliable.
However, if you shoot LF, perhaps something with spot metering (for zone system readings) would be more appropriate - and at about the same price of a new Euromaster.
If you want to try out the Westons, a Weston V can be had reasonably on xBay... Make sure the seller guarantees that it works as it should (accurate readings, etc.) - they can be had for $20-$40, AFAIK.
