I have an old lego suit case full of random pieces and i want to play with my nephew but i dont want to buy sets because most i have no interest in and they can be quite expensive as i was looking at them in the lego store. I have no problem buying a few loose random pieces as they have a wall of all random pieces in any color you can think of. Personally id like to see if i can build him barney the big purple dinosaur, hes two and loves him. Or a construction viehicle like a cement truck steam roller or excavator. I saw in the store on display but no set for a golfer made of legos id love to build that since his dad is a golfer and google is failing me.
Try first site listed below. Its got an inventory list of parts and you have sign up but it appears free. The second and third site you buy instructions but might be worth it.
