I don't like any of the Logitech models in terms of ergonomics. The Razer products I have to order over the internet and in my experience postal service is just awful so I'd like to avoid that. All of this leaves me with the following options:
Steelseries Ikari laser (which costs a fortune) or optical (which I can't tell if it's any good from the reviews)
Microsoft&Razer Habu (which seems to be flawed with various driver bugs)
Microsoft Sidewinder (looks uncomfortable)
Razer Krait
How can you not like Logitech mice? Thats blasphemy :O
About the mice you posted, I'd get the Razer Krait. It has an optical sensor (laser fails imho), 1600dpi (just right, you wont ever need more than that) and the sensor is pretty good afaik (wont accelerate in any direction if youre using mid-high sens).
If not that, get the Ikari optical mouse. 1st its cheaper than the laser one 2nd Its pretty much the same as the laser one exceot that its optical, and you can set anything between 1 and 3200 dpi on the laser one (eg 2476dpi, which is just unnecessary

)
Habu & Sidewinder I wouldnt recommend from what Ive seen on the internet.
Other than that, MX518 would be the way to go (or, if you like the Intellimouse ergonomics, Razer Deathadder, its pretty similar in shape and got a better sensor than the Krait).
