Anyone know a cheap place to get Logitech G430 Headset (Canada)

Nah. not really, as I said, take your pick of any of them.

My personal favourite is the true surround (4 drivers per ear) one that Speedlink currently has as their Medusa 5.1 (it's been used by Turtlebeach and many others though, I originally encountered the model as a CyberSnipa Sonar 5.1) purely because it's the most comfortable one I've used over the years and because it's relatively cheap. I have a big head and wear glasses so unfortunately fit trumps all else for me, not that it does too poorly in other areas though, and then there's the price VS the others.

She's actually coming to visit me this Saturday! We've been "together" [online] 3 months, but she'll be with me for 6 weeks as of the 19th July.

The G930 is wonderful, honestly. If you can spare the extra. The battery life is very good. You can charge it while you use it, or remove it whenever you want. The charge time to maximum is typically "about" 3 hours, but you get perhaps 9-10 hours use that way.

Basically, when you're sitting at your computer, you'd have it wired, just like you would have had to do with the 430. The difference is, you can wander off if you like and it's no problem. I've heard varied reviews on how far from the hub you can go, I guess it depends on the thickness of the walls in your house, but I live in a 3 floor house. My room is on the top floor, I can go anywhere in my house, even the garden, and continue my conversations or listen to music without any problems -unless- I go into my garage. Also, you can mute/ turn up or down /fast forward / pause /play songs or videos by pressing one of the hot keys located on the headphones themselves even whilst you're away from the computer. Convenience!

i have no clue, but its worth checking out & seeing if it supports Canada.
i live in the states, so i dont know what websites would be cheaper for you that are Canadian based, i figured id try & give you some options anyways, just in case.
