Despite the fact the conversions are on the pricey side I would also recommend you take a look at CH4D's 444 X Pistol Champ press. Reason is it allows you to run single stage at several different steps, it has a shorter press stroke than the Redding T7 which is a terrific press, but I doubt you want almost 4" of ram travel to reload 38 special or 45acp. Just offering this as a suggestion for something else to consider. I know that it is priced over the $350 price you mentioned, but it does come set up with a set of dies.
