I’ve only played 2.0 a few times at PATZ and VFW and am certainly drawn to the depth that the conversion opens up. I have considered doing the upgrade (are kits still available?), but haven’t for a variety of reasons (don’t have the funds for the upgrade(!), would rather use funds on another machine if the situation arises, don’t feel completely comfortable with modifying the original (even though it seems reversible), etc.). Based on things I’ve read here, it appears that the upgrade brings value, but I don’t have any direct experience.
Best of luck with the restoration! I look forward to following it if you’re planning to post updates.
