Hey ho to the waste & bad purchases.... I've made a good few mistakes & then there's the couple of quid here, a couple of quid there screws & bolts you need along the way - it all adds up. (I must have spent the guts of 30 quid on threaded rod alone!)

I've just bought some Astrosyn Nem23 steppers myself (Astrosyn don't list the ones I bought on Ebay - these ones have the most torque of all their NEMA23s)...cost me £69 for four (one will be used for my next pickup winder project). These will replace some woefully underpowered NEMA23 steppers taken from some old printers ....good riddance (though I'm miffed that these ones have 8mm shafts vs the 6.35mm shaft of my old ones ...poor planning on my part & now need to worry about boring out the holes on my couplers - yet again!)

But yeah...to anyone starting out on this journey....before buying wait, mull it over & then wait a bit longer - you'll save heaps!
