If it is an accutrimmer it says it just uses standard shell holders
As for the actual press it looks like you will need to buy a J to X adapter to let it use standard shell holders I would greatly suggest you do this as you can walk into most stores and buy the standard shell holders.
NOTE: What I said above may not be the case as per link given here http://castboolits.gunloads.com/showthread.php?223740-Modify-shellholder-to-fit-Spartan-Press
it seems you may want to test a "standard" shell holder (ie any RCBS, Lee, Hornady one you can buy in a store now) out first before buying the adapter. I would just buy one for the caliber you plan to load for and see if it fits, if not I would order the J to X adapter. This seems to be the case for some of the older Lyman presses.
here is a cross reference chart for all of the different makers shell holders
And when buying on EE always make sure to ask every question you can think of that will change how useable to it (ie does it have everything I need to do X with it. What would be needed to buy for me to be able to do Y.... etc.) It is always a lot nicer to get that stuff sorted out before hand, I am sure I annoy some people I buy from, but after the sale is done all is as expected and both parties are happy.
