Got the aeropress about a month ago and have not used anything since. Freaking love the results and how easy going it is! Next on the list is a new grinder, but unsure to go handgrinder or electrical.
Been using local coffee, labelled as French Roasted Coffee, it's pretty nice.
There are some great hand grinders available now compared to a decade ago. To get a remotely acceptable electric grinder you would need to spend around $150 or so for something like the Baratza Encore. For that same money you can get a really good hand grinder from 1zpresso or Kingrind which will produce more consistent grinds and fairly quickly.
