I had a little bit of free time this morning and out of curiosity, I visited the Lego® site to see if they might have old parts for sale. I have a Beta-1 Command Base that's had a few parts either disappear down vents, or get chewed by the cat, or just snap unexpectedly. It looks like all of my broken parts can be replaced without buying a new set, or rummaging at used toy stores. Right now, my shopping cart's at well below five bucks! I wonder what shipping and handling will add to the cost. The scary part is that seeing all of these bricks and specialty parts that I've never seen before are giving me ideas for building my own kits from scratch, or modifying existing kits. It's really exciting. I could easily design a model on scratch paper and then order the parts and build it. The Aquarion DVD showed the show's creator with a working, transformable Lego® model of the mech featured in the show. A Sun Cobra model might be fun to build with a fully articulated tail.
