Never pay full price for anything
(someone has it on sale for less)
Never buy things on sale
(they are end of line and about to be replaced)
Never buy "new" things
(the "a" model never works properly)
Never buy Chinese imports
(made of "chineseium" and not a patch on "genuine" machines.)
Never buy old kit.
(tho a solid relic of the empire, likely to have been flogged to death over its existence)

What I have had, is a fun stab at producing ever more accurate and complex swarf, finding more and more efficient ways to clear up the mess I've made, and, learned a lot, some about the machines and tools, and some about me.
For a rank begginer, the hobby is one step forward, several steps back. However, over a career in the oilfield I've learned enough swear words to keep me motivated.
The more I learn, the more mortified I am at how little I know.
But I know more than I did last month.
