I'd say go for the Esprit, by the looks of it, the EON still uses the same focuser design as their doublet series. The Esprit uses a HEAVY duty 3.5" focuser built like a tank with built in rotator rings and focuser rotator as well. You'll have no issues with image tilt. Not to mention there are more people who own the esprit here in australia so they'll be better online community for support if needed.
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.
I've heard that the first generation Esprit had focuser issues but the QC on the later models were much improved. The focuser on my 100ED has been nothing but an absolute solid performer. But, I guess it's something to consider.
The TS 130 triplet in the classifieds with Moonlite focuser is a good deal provided it's in good condition. It would be of similar weight to the Esprit 120.

After some further research I think I'll stick with the Sky Watcher. Unfortunately my budget doesn't stretch that far at the moment so will have to wait until I have the money.
