What does everyone else use/recommend? I don't mind spending some money provided that the gear delivers and lasts - I am not terribly tough on my gear. I will always bring along some tablets and coffee filters as backups, but I feel like it's time to spring for something a little better.
I will do most of my backpacking in Michigan (not always many clear water sources), but I would like something that can "go anywhere, do anything" (I realize this is impossible, but I would like to be covered for the majority of the situations I would ever find myself in). I guess my favorite backcountry destination would be the Sierras, so I don't know if mentioning that makes any difference.
