IMO the later Insights just became special snowflake Priuses, they lost the things that made them unique. The CR-Z from the 2010s is the one you want, they were still sold with a 6-speed manual even, although that car has it's own drawbacks as well (relatively heavy, MPG could be better, performance isn't that great to make up for it either).
Unlike trying to find an old Insight however you do see a fair amount of these for sale, and with manual transmissions as well.
