ok, I just did a search (you're welcome Lordathestrings!) and couldn't find any posts like this one... ok... so I've heard alot about metronomes being a great way to practice. so I decided, "I ought to get me one of them" but I have no idea about what is essential in a metronome, or which one to get... I would like to stay as inexpensive as possible. and I don't need any optional features, such as a tuner. Any input is appreciated
