Typically you can compensate for the lack of micro adjustments by varying the dose. E.g. of the next finer step is a bit too fine, drop 0.5-1g from the dose to balance the flow rate. Of course you need a scale for that but I assume you'd want to have a scale anyway, even if it's a more general cooking scale. Am I wrong?
For the money, the Encore ESP and the Fellow Opus are the only two good choices in the under $200 range for electric machines capable of grinding espresso level well. The video reviews seem to show it does a decent job for grinding espresso.
The difference between pre-ground and grinding at home where you can adjust the grind should be significant. Haven't used Encore ESP but it should be fine. It seems like the default choice performs well while not breaking the bank. I'm using a Sette 30 but I bought that second hand.
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 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.
