Craiglist is a wonderful idea since your on a budget. You can find some great deals plus negotiate at the prices. My tip is bring a friend with you. try to look for solid wood it last longer. if your going buy buy Pre-owned Don't be afraid to open up the drawers and see if its real wood .
Wiggle the furniture to see how sturdy it is, look at the dove tails they should be nice and strong. Don't be discouraged about any scratches on the outside that can fixed. That whats so amazing about wood it can be stained or painted. I have seen some great deals posted on Craiglist either people are moving or they need the Quick Cash. Have fun & Good luck in searching for that gem
