Buy a Kit or individual LEGO Pieces
Recently a young boy came to my house with his grandmother asking if he could borrow some pieces to finish his MOC. With nearly 200,000 loose pieces at my disposal, I told him I would be happy to give them to him. I guess I should of asked what pieces he was looking for because he asked for some rare pneumatic pumps. LOL! Because I already said yes, I just gave them to him, but then his grandmother asked if it was better to buy individual pieces or to buy a set and use the pieces in there. The answer is yes and yes.
It really depends on several things. If your looking for very rare pieces, like the LEGO Part 53178 – Pneumatic Cylinder Bracket and paying anywhere from $20 to $48 per piece, it might be better to buy the kit, but if you want several pieces from different sets, it would behoove you to buy them separately.
Nobody really knows what will be a rare piece and what won’t be, but you can have a good idea if you know where to look. Even thought the suspension on the 9398-1 Rock Crawler are new and exciting, the odds are they’ll produce more of them so I wouldn’t go out and purchase another one just for those parts.
It all comes down to necessity. Most of the time, if you’ve been building your inventory, you’ll only need to buy individual pieces but if you find you might need several pieces from the same set, than I would suggest buying the set.
The best places to go to purchase individual pieces are: http://shop.lego.com/en-US/Pick-A-Brick-ByTheme (for current sets only. They discontinue pieces and they’re the most expensive), www.brinklink.com,(Individual stores through out the world offering nearly any piece ever made) and www.peeron.com (Similar to bricklink.com). You can also buy a lot of used pieces off of Craigslist. People are always trying to get rid of sets or boxes of pieces. GOOD LUCK!
