Good.  I hope you like what you find.  It does take some trial & error.  It took me a while before I found local roasters who actually knew what medium roast meant.  Too many around here were trying to appeal to the Charbucks crowd.  That was maybe 5-10 years ago, and I think it's probably easier to find good local roasters now.
$250 for a hand powered grinder!?  That seems like way too much money.  I wonder where you read that?
I had a simple electric twirly blade grinder that I used for decades.  It was a wedding present.  It always worked well, taking about ½ a minute to grind beans fine enough for a drip maker with a Melitta type filter cone.  After 30-35 years it bit the dust.  It was so old, that it said "Made in West Germany" on the bottom.  And I bought another one, a Bodum Bistro, probably made in China.  It was no good from the start.  After about ½ minute of use, the grinds contained a wide mix varying from coarse hunks to fine dust, and everything between.  The fine dust clogged the paper filters I used.  So, I bought an electric burr grinder, 
a Baratza Virtuoso,  which cost $200 at the time.  I probably paid too much for that, but I still use it today, after 7 years of daily use.  I also have a 
simple hand grinder as emergency back up in case of power failure. I paid about $25 for it 10 years ago. I've used it 3 or 4 times. By the time I finished grinding the beans, I no longer needed coffee to wake up.
If you make espresso with a high-pressure electric espresso maker, 
such as a Rancilio Silva M, I'm told you need to grind much finer, such as with a 
Rancilio Rocky Grinder.  Those prices keep me, and others, away from ever going there.  I have never heard of any hand powered grinder that costs $250.
I don't think an Aeropress needs anything like that level of fine grind.  Here are some 
examples of electric grinders and 
examples of hand grinders recommended by a reputable online coffee product vendor. (Don't bother with that $25 Bodum Bistro).
I don't know if I made myself clear enough earlier, but I have nothing against Aeropress.  It's another coffee brewing tool that works.
