I've no experience with the EON, but I had an Esprit 120 and loved it. Sensational telescope. I'd still have it to this day but the humidity in the observatory didn't agree so much with the optics (had fungus issues).
I'd say the focuser was pretty average. I spent a lot of time adjusting it because it couldn't hold any weight when I first got it. I ended up replacing it with a Moonlite and selling it to someone (who knew its condition) who apparently spent a lot of time getting it into a decent working state. I'd expect to have to replace the focuser, but you might get lucky.
