I've been wanting to get a new personal timer, the kind that you can strap to your arm or something. I can only find the $15 or $20 ones on Title. That's expensive for me. Are there any other options? I would like this thing to be reliable, convenient, and cheap. If I have to get the $15 one, I will eventually, but was just wondering if there were cheaper options. Thanks. EDIT: One I can carry easily with me, by the way.
