Our coffee grinder just broke and we need a replacement, but we don't have a large budget. We aim to spend no more than $50 and I am trying to decide if we should get a cheap burr grinder or not. The only cheap one that got okay reviews was the Mr. Coffee, and even then the reviews were not great. Do people think that it's better to get a cheap burr grinder, or use the money to get a slightly nicer regular electric grinder? I've heard raves about burr grinders and others that say it doesn't make much of a difference. I can't decide if it's worth it if it's just going to be a so-so one. Anyway, any input would be appreciated (including brand recommendations). Thanks!
