I've never used the ESP, but it has stepped adjustment which is not ideal for espresso. You only get 20ish grind sizes to pick from, and you'll probably end up using 2 or 3 of the available grinds. You'll be wishing for "in-between" settings because espresso is very finicky.
The original Encore had pretty inconsistent grind, with lots of big chunks, lots of fines, and plenty in between. This isn't ideal for drip coffee, but it's fine. For espresso, if the grind quality is similar, it'll give you a lot of frustration.
A good espresso grinder is expensive. Home espresso is expensive.
My main point, though, is that it's stepped, which a good espresso grinder shouldn't be. There are other, more expensive, stepped espresso grinders which I also don't recommend.
Something like a Eureka Mignon Silenzio has stepless adjustment and flat burrs. Yes it's more expensive, but I always recommend buy-once-cry-once with espresso stuff. Trying to make espresso on a budget can be frustrating. Espresso should be fun!
I get where you're coming from, but getting a grinder that makes making espresso frustrating might prevent someone from ever enjoying it. I'd be more likely to recommend a similarly priced hand grinder that can be retired to travel or pour over duty once funds are available for a nice electric espresso grinder
I have the original Encore, and I ended up installing the M2 burr upgrade for this reason. The stock burr was actually bad enough to cause problems for filter coffee too.
