Ok. Not to start $h!t. But,NIB G20 can be had for $550-600. Post up what your build ends up being. 80% can be made on a budget. But, they aren't cheap.
Don't forget to pay MD Tax and Hemorrhoid fees.
I've never had a build above $475, but that could change...
Look for a sale on any given day and you can beat these by 10%. Be a savvy consumer and be really less.
