It all adds up! Be it, not quite the right module, or software that won't do everything you want. The base HS3 is extremely powerful and allows a tremendous amount of latitude. It's not unusual to have to spend a few $$ more to make something the way you want it. Options! Imagine, nowadays, Adobe rents you software and others are headed that way. At least you own HS3 and the plug-ins you choose to purchase.
Luckily, HS3 allows integration of these options as opposed to having to run another program that doesn't talk to the first one. HG has this potential but the $ model will never support the creator. AHP could have been it all, even they had separate add-ons, but alas we know where that ended up.
At least HS seems to be able to keep up with the economics and the advancements of the technology.
