I had been loading 6 years before getting my first chronograph, a CED millenium which is a good system but more recently I splurged on lab radar. The CED had some advantages such as you don't have to worry about stepping in front of it while it's on. If your loads are accurate and you get a good practice session in you don't need a chronograph. The chronograph will let you compare loads and refine your consistency a bit but if you are using proven recipes you are fine without the chronograph.
