The smaller the LEGO creation, the bigger meaning individual parts have. Black thin elements in the middle are in fact motorcycle body, and slightly slanted side modules are made out of minifig upper halves (de-handed, obviously).
Roughly 2/3 of all my pieces are from "special orders", but it is really cheaper way than buying a set. For example, case of this speederbike. A motorcycle frame which I needed costs around $0.20. A smallest set with that motorcycle costs at least $4... if bought online.
Generally, from my experience - for serious building, bulk orders are better. So things like 500x of plate 1x2, 500x plate 1x1 and so on.
For inspiration, however, sets are better because you pay for much more *types* of pieces.
...then there is that unique aspect of LEGO building: whatever you don't like can be dismantled and used for other models. You cannot do that with paint, cardboard models or plastic glued ones
Brilliant Idea and your putting it to Amazing use!! Thanks for that I've always liked the space kits anything that look futuristic so I was always buying them but at practically 60 a pop that got old quick Ha! But they way your doing this is Perfect love it man!!
