It's been a while since I've been around, but I still game from time to time when work/life allows me to do so. I'm currently running a Logitech G400 (might be a rev.2, but don't rightly recall at the moment) and while I do really like the mouse in general, I kinda want to move back to that MX300 type of shape. I do have a G100s, but I need a thumb button or two that I've gotten used to using in games.

I hear a lot of people raving about the Pro and the 3366 sensor. Sounds like a good mouse to go to, but that $70 price tag though. I see the G203 of very close to the same dimensions, but it seems like its using a different sensor. Not sure which one or how good it is, but $40 is a much easier pill to swallow. I'd like to stick with a Logitech, but if there's something else out there that might fit the bill for less, then I'm interested in hearing about it.

Looking forward to the suggestions. Thanks in advance, guys.
