^^ Cost wasn't an issue in Vancouver. The only reason that the latest metro line is a different technology was because the RFP basically asked for it (no shared equipment with existing system). If it wasn't a requirement, it would have been cheaper. However, the next line (Evergreen), which will start construction in a couple of years, will be Bombardier ALRT....as previous attempts to make it LRT were strongly opposed. Also, it looks likely that 2 more extensions (Millenium line to UBC and Expo line further east) will be Bombardier ALRT. So I would say they make a pretty good system.
