I ordered a SDB set up for .38 special, a primer flip tray, a spare parts kit, and a 4-pack of small primer pickup tubes. It all came to a shade over $460, shipped.
I figure to load 7000-10,000 rounds of .38 special and a couple thousand rounds of .357 magnum before I think about needing another caliber setup.
Got a bunch of hoarded components to turn into loaded ammo in the next year or so.
I use an SDB for 45acp, 9mm and 44 mag. I find that I usually do 1000 round batches at one sitting nowadays. Funny, but when I used to shoot a lot, I would do 400 round batches once a week. I much prefer to shoot than reload, so I really like the SDB for getting the reloading done. The only time my SDB gives me grief is when I try to use it in 50*f temps - the little primer release plastic thingy (technical term) doesn't want to flex correctly when cold and will sometimes double a primer.
I reload my rifles on a Lee Classic Turret as I don't shoot enough to warrant a progressive (maybe 100 rounds a year at most).
