One Shot really is worthless.

Dillon's Cas Lube or the equivalent homemade mixture of Lanolin and 90% rubbing alcohol really is idiot proof and a little goes a very long way.

I'll second the recommendation for Imperial Sizing wax. Another one of those products that just can't be beat and a little goes a long way. I've still got a 3/4 full little tub of it that I bought probably 3-4 years ago.

A Rock Chucker single stage is a can't miss, great first press and even if you decide to get a progressive later; you won't ever want to get rid of the single stage. Ever.

Lee actually makes what I believe is the best hand priming tool. I do like my RCBS bench priming tool though.

Don't even consider using SS pins when wet tumbling 223 brass unless you are a glutton for punishment as it is a time consuming PITA getting the pins back out through the neck. I love shiny brass inside and out but it is ridiculously time consuming.
