Replicator 1 Dual Parts and Upgrades

This is a list of suppliers (with links and/or part numbers) for drop in replacements or upgrades for the MakerBot Replicator 1 Dual 3D printer. Most of the parts listed currently are probably not correct, but are the closest I could find.
I am initialing my approval [ --CLF] if I think the part is appropriate for the Rep 1. Feel free to do the same.
Please add a note if an entry is obviously not appropriate for the Rep 1 Dual.
If MakerBot is the only source for a part, please note that.
If some parts require a modification to work with the Rep 1 Dual, please describe the modification.
