I second that smiggle leak horribly! Most typo water bottles do as well, or break quickly.
We've had every type of drink bottle and totally agree that cheapest is best as the get lost; the mouthpieces get chewed or gross in bits that are unreachable; steel ones get dented and get little rusty looking patches inside; plastic ones start making the water taste funny...
I have just bought the $5 cotton on kids ones previously mentioned (available in plastic or steel) so will see how they go.
