Some good ones I'll steal here which didn't jump to mind:
Cheap case trimmer - especially Lee hand trim crap
Roller type Lube pad (One Shot 4 Lyf!)
Hornady OAL gauge spindle and modified cases
Plastic powder funnels
Then I'll up the ante with:
Hornady Lock-n-Load AutoCharge dispenser. First one went down after about 15 months, just out of warranty, so I bought another. Second one went down within the 1yr warranty, so they replaced it. Third one went down just under 18mos. 3 machines in barely 3 years.
And in fairness, I regret buying 2 RCBS Chargemasters & a Lyman Gen5 Great units, no real complaints for what they are, acceptable level of overcharges here and there - otherwise repeatable - but so ridiculously slow. Regardless of the increased price, the Sartorious and auto-trickler & auto-throw are more precise and take 1/3 the time - actually keeping up with the seating process. Instead of having 3 dispensers throwing, now one does the job.
Hornady Concentricity Gauge. Everybody likes to own a concentricity gauge it seems like, but I'll be damned if I think it's worth the price - I haven't found corrected ammo shot any better, and making concentric ammo on good gear is faster and more accurate than trying to fix it later.
30-30winchester dies - just in general - I largely regret reloading for 30-30 at all.
