I load all four gauges on the old 800B because I like the full length sizer die. The short sizer dies on later "improved" models that allow a taper crimp are not an improvement in my opinion. Consequently, I choose not to invest in the later loader models and am still loading on my seventies vintage 800Bs. Once in a while, I buy an accessory that is truly an improvement, like the quick change bushing feature, and the counters, but no need to buy a new loader. I am not familiar with the new primer feed, but will look it up on the website or get Jim Cunningham to show it to me next time I see him, probably next month.
