I have around 30-50 running the Casino/hotel at which I work and they are amazing.
I've had no downtime (Other than the 1-2 minute updates annually) for the past 5 years.
They are workhorses and have lasted way longer than any other access point we've used here.
I got 2 of these not long ago.

Seems to do the Job for me just fine.
Can't remember exactly how much they cost me each.
I bought a GT70 MSI 17 inch a couple years ago, it still plays games with decent settings.
I've owned an Alienware before, I like my MSI Laptop more.
Good luck mate.
I would check out Razer.

It's 6.5 pounds, but not bad for a 17 inch laptop.
Thin too.
Not an 880, sorry. But meets other requirements.
