Some perspective:
A really good grinder will allow your Gaggia to produce the very best espresso it's capable of producing -- which isn't really very good in the greater scheme of things. In fact, a really good grinder will allow a really good espresso machine to produce the very best espresso it's capable of producing -- which, considering your little Gaggia, isn't really germane.
H-B is filled with people kvetching about their Baratza Virtuosos; no one seems happy even after they get them to grind finely enough to get something which resembles an actual "espresso grind." At least, they're not happy for long.
Moral of the story? That a given grinder can grind fine enough for espresso isn't enough. The hallmark of minimal adequacy when it comes to making espresso is the ability to make very small adjustments and get consistent results. This reflects the differences between coffees, and the changes which occur as a given blend ages and/or as the atmospheric conditions change. And, espresso machines impose their own limits on quality; they can only do what they can do.
Getting down to cases...
I can't speak to the Krups -- never seen let alone used one.
In my experience, when it comes to new, electrically powered grinders, at 3 bills a Baratza Preciso is about as inexpensive as you can get and maintain enough control to tweak your coffee meaningfully for an inexpensive espresso machine; and, not to pound the point to hard, it's an appropriate grinder for your machine in the sense that neither would outstrip the other by much and no expensive capability goes begging.
A good used grinder, or an OE Pharos (if you can deal with the exertion and kinky spanking) won't hurt anything, will cost about the same, and will leave you ready for the step up to your next espresso machine. But used isn't new, and hand powered isn't electric.
Preciso, used whatever, Pharos -- each of these choices has its strengths but none is perfect, and each is going to end up about $100 more than your stated budget. Little to spend often means lots to think about.
