I've bought a JavaPresse manual grinder a while back. I'm pretty happy with it. especially the portable factor. I can take it where ever. In fact I took it to a camping trip about 2 months ago. works just fine. the only problem I do have with a hand grinder is that fact that I gotta use my hands to grind. But that's the only way I can get freshly ground coffee if I'm hiking in the middle of nowhere.
As far as the price goes for the JavaPresse its fairly cheap I got mine for $40 bucks but that was a while ago when it was on sale. Right now I think its about $20.
Quality: I'm kinda amazed at how good this grinder is made especially when you think about the current price of $20. It pretty sturdy.
Looks: I'm not that impressed with the looks though but then again thats just me I like things that look totally cool you know like 007 type of gadgets. Don't expect this hand grinder to be anything like that. It just plain and simple looking made of stainless steel. and does what it is meant to do grind coffee anywhere without electricity.
Come to think of it if it was made to look really cool then i guess the quality of the grinder would not be so great. I'm guessing the only reason this grinder has lasted me a long while is because its made of stainless steel. On my trips I have dropped in many times. but the only thing I noticed was minor scratches on the body. still grinds great coffee and everything is working just fine.
If you want one then I would say the best place to get one would be Amazon since that's where you can get it the cheapest.
