This has been my daily drinker for about a year now, $25 from Amazon. The only real competitor is Contigo, a little cheaper but you can't field strip to clean it like this one. One caveat, I do sometimes get a little leakage when I fill with carbonated beverages (not recommended) and don't leave enough head room.
pluvoIf you like the Contigo-style spill-proof sipping, Camelbak's system also stops accidental spills and is much easier to clean. (They're also tougher when dropped.)
The Zojirushi is an amazing mug for heat performance. Thermos/Nissan makes a similar bottle-style mug that's a bit more durable, but if you don't drop it on concrete the Zojirushi is probably the best it can possibly be.
