Are you using Linux or Windows?
I tried a Linux Live CD but, the client had pre-reqs and it looks like you need a full install. I get 10Mh/s currently in Windows 8 using one eVGA GTX 960 but, it crashes the driver after a few hours. It seems profitable especially at $12. I want to take the plunge and build a real mining rig however, I'm nervous the profits might not last and I'll regret it.

I'd personally hold if you feel the price is stable and/or going up. Otherwise if you want to be conservative convert to BTC on an exchange.
You can search down cheap psu and cheap gpus - these you can resell for the same money more or less within 6 months if they don't break. Mostly it's the fans that go wrong. Mine used to leak some kind of oil and the gigabyte ones catch fire so don't have them near any kind of mosquito nets or stuff like that. This is rare though and only gigabyte 7950. I actually did catch fire to a small part of netting that was blowing near the machine. Luckily it only happened when I first turned it on so if i wasn't there then perhaps something worse.
However the good thing about gigabyte is they have a long warranty period and so do xfx so you can get free repairs or if it's fans just stick case fans on with high temp resin - actually works well. I like the sapphire cards most they are quiet and ive had no fan issues with those. Even better if you can get ones with 3rd party expensive coolers for the same price.
If you get lucky you can build a very cheap rig and if ethereum crashes you can keep for the next POW coin (sadly most are ICO now) or sell and you will not lose much other than postage and selling fees.
