It's a really nice mouse, i gotta admit.
If I HAD money, i would definitely pay 70-80 for it, but with bills and struggling to keep food in the house for 5 people on a 3 person budget.. spending money isn't an option.
I feel you, having the same struggle right now. Just lost my job when i have to support 3 other people in my house. Put in over 100+ applications to just about everywhere.
Pretty much anywhere, its a super solid mouse with a perfect sensor and lots of features, so many places will stock it since it's a really popular model.
I got mine at CanadaComputers recently but I'm pretty sure you can find it online at a discount, shouldn't be more than 70-80 dollars but I've seen it drop to 30-50. Just a note, the mouse is VERY heavy for a FPS mouse even when the weights are removed, so if you're moving to this from a Deathadder or a cheapo generic brand mouse it might actually hurt a bit to use.
