Best wireless keyboard for heavy duty typing?

So I think my cheap as heck keyboard (which is about $20) might be going into the dust soon. Space bar gets stuck a bit and I think it's the sign of the end soon. So in the event this happens, what keyboard would you all recommend? To mention how I use my keyboard I'll leave some stuff here:

• I constantly type a lot; typing is what I do just about 99% of the time. Due to this, my space bar is always worn out and I'm already on my 3rd keyboard here on my 6th month.
• I game a lot as well. The keyboard is necessary for gaming; add this onto the above and you can tell I do a lot of heavy duty stuff without taking a break.
• Something that will be durable regarding keys; I don't want my space bar constantly being stuck or messed up due to heavy typing.

With that said, can you guys help me figure out which keyboard would be good enough for me to have? I just want one keyboard that's going to be literally durable for a whole year instead of having to switch it out more than three times a year. >_>

Thanks for the links! Money hasn't been an issue for me since a keyboard is something I heavily use. The most expensive equipment I buy are mostly electronics related so no issue there. :3
