Wow, awesome! Thanks. Guess the submersion cost thing isn't like "official official" yet. Was hoping to have something to show my GM, looks like I'll have to pay the 30 karma unless he agrees with no proof.
Hero Lab is sometimes used for rules checking. The errata, as far as I know, hasn't been updated recently; despite being a "living" document.
Here is a quote from Michael Chandra in the Rules FAQ thread.
So..would Hero Lab count as Official Clarifications? If so:
1) Yes, the cost of internal Smart Links is just the price of the weapon.
2) The whole issue with Submersion being multiplicative is additive
As far as I know, it is intended that Submersion is 10
+ (Grade level x 3); it was simply a proofreading/printing error.

As a personal opinion, your GM shouldn't be penalizing Technomancers that much. Even if it wasn't RAI, I would say it is additive, not multiplicative. Technomancers are already behind most other archetypes, especially their mundane counterpart, the decker, by quite a bit. There are plenty of threads and math to back that up. Giving them a small break such as that is not going to make the game fall apart.
