Yeah, if anyone finds a source, I'd be very interested - I've written to several mfgrs and so far they don't want to split kits.
I'd love to get individual parts more so I can creatively combine them - I would like to mix and match, and I like certain transmissions better than others. Of course, I too have messed up the occasional transmission...
I purchased a package of 5 transmissions for slimlines from a Woodcraft Store, but the 5 pack cost $8.50 ($1.70 each). When you can buy entire slimline kits for $1.70 the 5 pack I purchased isn't econimically feasible----might as well have the extra parts and buy a kit. Would also like to see a cheaper resource for parts.
I wonder how many center bands you can put on one pen and still have it look interesting? Would be one way to use them up!! I'll have to think on that a while.
