Fox, if you are refering to the Hybrid, then no upgrades needed mean no upgrades available, at all. If they are indeed needed or not, that's another problem, but the fact is that most Hybrid owners are not complaining from lack of third party support...
The new version has an internal RAM(not upgradable), an integrated LPR(not upgradable), delrin sleeved hammer(not upgradable), and a three-way(not.. err, it is upgradable)
Personally, i like the idea of buying the complete body kit and adding a racegun or an E-blade to it. It's probably the cheapest electrococker you can build, but by far not the worst performer.(there are not enough available reviews of it's performance in comparison to the Freeflow/eclipse/ccm cockers, but also there are NO bad reviews on it, at all!!!!)
