If you've already invested in a FX-120i for reloading, then trust me it is worth it to save up for the V3.
The first time I used the new V3, my grand daughter was helping me like she does from time to time with reloading. She grabbed my phone, figured out the new app and had the thing going in no time. She was laughing about how much easier it was than the old V1 method or what we had done before that.
Don't worry about other added expenses like the Area 419 accessories as you don't actually need those to make the V3 set up work extremely well. The only other thing you'll need to figure out is how you want to get the powder into different size cases effectively. The most cost efficient method I have used is the old Lyman powder cup with a funnel on it as it seems to work on a wide variety of cartridges.
