I hope this is the right place for this... I didn't want to put it in both the 550 and 650 categories.

I'm kinda torn between the 550 and 650 machines.  Any advice or shared experience would be appreciated.  I'll primarily be reloading .45 ACP, but there's also going to be .223, .40S&W, and a distinct possibility of .308, if I ever get that FAL built.

Bottom line question: While the bare-bones prices are similar, I assume I'll need a casefeeder to get the most efficiency out of the 650, correct?  Is there anything else I'm missing in that equation?  (I assume I'll need more primer magazines, toolheads, etc for either reloader.)  Does it make sense to start with a 650, then add the casefeeder later?

Also, what's your experience with ease of use, need for adjustment, etc of the reloaders you've used?  I've reloaded before, but I'd rather go with the simpler and slower machine than have to make a ton of adjustments every time I reload, if that makes any sense.

Thanks for any advice, and Merry Christmas to all,

WoodyTX
