Ambidextrous mice

[xolectic]

I am a right handed person but it turns out that I am not a fan of right handed mice.  I bought a Logitech G400s mouse recently after seeing the rave reviews, and I have to say that it doesn't feel right in my hands.  I am just too used to ambidextrous mice.  With that being said, what are some good ones?  I bought a Logitech G100s because I like the shape, but I considered buying a Razer Abyssus.  I have also heard great things about the Zowie FK and AM, plus the Razer Taipan and Ouroboros but those are a bit pricey.  I used to be a diehard trackball user, but I would not use the Trackman style ones (except the Marble).  Who else thinks ambidextrous mice are better?

I don't think that ambidextrous mice are better but they just fit me better.

Zowie AM/FK is very good, although far from perfect.
Kana v2 if you want a smaller mice but not as tiny as Abyssus or G100.

I really like the old Microsoft Optical Mouse 1.1

There is a Logitech from the same era that is almost as good, if you like a narrower profile.

Caseless G9x is what I use

For ambidextrous mice, I like using the Abyssus. However, I've been using the CMStorm Spawn and Logitech G9X recently. If you want some more information about mice, check out vun's writeup on them.

Zowie FK/AM but they may be a bit smallish

I'm using the Zowie FK at the moment. I really like it for my small hands using a palm grip. It could be good for someone with larger hands using a claw grip.
It's very light, the main buttons are a bit hard to double click, but I think that could change over time. There's no rubberized coating so it looks kinda greasy on my desk, that's the only downside for me. I want to get a second one for my work because the DPI step (2300) is just perfect for me.

Another one to look at is the CM Storm Recon-- I returned it because it was a bit too large for me. The buttons are really clicky and easy to click. It looks really cool with customizable LED colors and rubberized coating. The other thing that bothered me were the DPI steps as I found 3000? DPI too high but 1800 DPI too low, and there's no way to modify those steps in the software. I think this mouse is made somewhat with a claw grip in mind due to the angle on the back of the mouse (if that makes sense).

If you wanna compare some mice sizes/prices/sensors check out this Google doc-- originally from reddit/MouseReview, I updated it a bunch when trying to decide what mouse to buy online.
