dude,
i bought my g400 in autumn 2011 for 30 euros. at the end of the warranty the cable started to randomly disconnect, so i sent it to logitech support and got the g400s as replacement.
even if you want to buy another mouse, you should do that and sell the brand new replacement, which might be the g402.
edit: dunno how clocks run in turkey, but in germany stores have opened on saturday and the the sending date of packages is of relevance, so both options still would be within the 24 months warranty.

Dude, repair your mouse. You can just repair the mouse.
You can either solder the cable (always breaks right where it leaves the mouse) or just replace the whole thing.
Logitech makes enough money from the average consumer that buys new mice for whatever petty reason. But if you are somewhat dedicated to PC periphery a cable issue shouldn't leave you wanting to buy a new mouse.
Alternatively, just contact customer support. Not all that rare that they will still respond, especially if you are just a few days out of warranty. Of course, the G400 is EOL'd, so you will get a G402 or something.
I had MX500, MX510, MX518, G400, G400S. The G400/G400S are the best mouses I've tried so far, it's awesome that they have 1000hz out of the box, it was a PITA all the time configuring usb polling rate etc. Even tho, tbh G400S looks like shit, and too much "gaming" for my taste.. it's still an awesome mouse.
My first G400 died after 3 years, they still gave me warrantee meaning I got a free replacement G400. After my 3rd G400 died I'm now using the G402, very good maybe even better and very similar feel to it
I've gone from mx500 to mx518 to G400 to G402, I would say it feels close to the same, except for the button on the left side which is slightly annoying but u get used to it. the right side of the mouse is slightly steeper but you get used to that after a couple of days as well.
The sensor is superior to all the previous models (never used the g400s). I'm very happy with it and it didn't take long to get used to it, hardest thing was the mouse clicks which are slightly heavier meaning you have to press a little harder. Once again that takes a few days and you don't notice it.
The overall build quality seems a lot better then the G400 and it's slightly lighter, the cable is slightly thicker/heavier which was the main problem with the G400.
If you loved the G400, you'll love the G402 given a week to get used to it.
Um, instead of a G100s, consider a G302. It's better. The Kana V1 is better than the Kana V2 because the V2 has smoothing up the butt, so get a Kana V1 if you can, but prepare for the bad mouse feet. The Abyssus still jitters when you move it vertically (I know because I bought one two weeks ago and am going to return it.)
But really you should just get a new cord for the G400. It uses a plug-in cord, so it's ez to replace.
