To make the Dillon 650 really "sing" consider investing in several non-standard options, I did and highly recommend the following:
1. Case feeder
Not really optional, this will greatly speed you along.
2. Roller handle
Again not really optional, the stock ball-on-lever will make your hand sore, without this item your reloading may become more of a chore rather than a zen-like experience.
3. Strong mounts
Even if you build a sturdy 2"x4" bench and lag bolt it to a wall the press will seem to wiggle slightly during the top and bottom of the lever stroke without this option. Also it adds some height to the press which allows you to make your reloading bench at a "standard" height. Otherwise to have the press at a comfortable height your bench may be too high. FYI I'm 6' 1", YMMV.
4. Bullet tray
This lets you place a large pile of projectiles right next to the bullet seating stage and greatly increases your throughput.
I have found no need for extra primer tubes, they wouldn't save me any time. Then again I don't have an automatic primer filler, in that case the extra tubes would be a value-add.
Expect to build a strong bench. As mentioned earlier a 2"x4" (minimum) framed structure lag bolted, to a solid wall.
