I'll spend as little as possible.
But I won't buy cheap, poor or questionable parts just to save money. I'd rather have one quality AR for the rest of my life than several "OK" guns.
I'm currently putting together a budget build and expect to have around $350 cash into it when I'm done. But that's because I've been shopping sales, scavenging parts and picking up brass to sale or trade for parts for over a year. Not because the parts will be of poor quality.
