Another vote for the Lee Hand Press and a set of dies with a dipper.
I highly recommend the hand press over the Lee Loader for one reason.
No one here has yet told you that you need one more tool in order to use it.
A HAMMER. 'Nuff sed.
In case of an EMP bomb, a zombie apocalypse, a SHTF scenario, or we get thrown to the wolves, the hand press is very, very portable. And .38 cases can be safely used dozens of time over.
Breech Lock Hand Press Kit $50.
Lee three piece Die set in .38 spl - $30.
Lee Precision Modern Loading Book - $20.
Forget the scales, forget the calipers, just stick with the recommended powder selection and use the dipper properly and you can SAFELY use this setup. In my admittedly non-expert opinion, this is the most inexpensive SAFE alternative to getting into a bench press.
This will allow you to find out whether reloading is for you or not.
And for the purposes of "how cheaply can I do this", you don't need to tumble .38 cases. They shoot just fine dirty. Or, there are rumors of folks cleaning them in the dishwasher, i a lingerie bag, when the boss is out of the house.
