Furniture advice

Where is the best place to buy an affordable but good QUALITY furniture set (changing table, dresser, and convertible crib) that'll last my baby until baby is much older. We picked out a furniture set at buy buy baby, but it is SO expensive & now I'm having second thoughts. The furniture at target seems much more affordable but their sets typically only contain 2 pieces (the crib & changing table/dresser). Any advice? My little one has a pretty large room & I would like some bigger pieces to fill it with lots of storage!!
