Here's my 2 cents, get your grain of salt ready:
I started with a Hornady Powder measure, trickler and scale from my LNL kit, I quickly learned there was no way in hell that was going to work.
I upgraded to a Chargemaster 1500 thinking I had found the magic formula for accurate powder charges, wrong. Even with consistent neck tension, seating depths, it was very hard to get a load in to single digit SD's. I was using good equipment, annealing my brass (not over annealing), using good brass, you name it I was doing it. I still couldn't get the results that made all the time and money seem worth it.
Not too long ago, I sold the chargemaster and picked up an FX120i. I remember looking at these thing however many years ago it was when I got into this hobby/addiction/illness/etc. and thought who the f*** pays that much money for a scale. Now I know why people do it.
The first load I put together with the FX-120i had an SD of like 3.4 on a 5 shot group, I was/am extremely happy. It also showed me how inaccurate the chargemaster was. In my 6.5 CM I was shooting 41.5 gr of H4350 behind a 140 gr Berger VLD, my Labradar said it was doing about 2750.
I put the EXACT same load together with the FX-120i and the speed jumped over 100 fps. Same bottle of powder, same brass, primers from the same box. The only thing I changed was the scale.
IMO, buy once cry once and get the 120i.
