Starting out my build. Any advice will be greatly appreciated!

Sell it, buy a new one.

You’ll only loose 200 to 250 selling on Craigslist.

Now, if that is your budget go ahead and buy the best one you can and go at it. Who knows, you might turn out to hate the biz? You’re young and i can tell you have the drive so wether u buy a $400 machine or a $4k one I’m sure you’ll do well. Stay debt free my friend!
