PC resellers will generally stock what is politely referred to as OEM RAM.

"Generic" - read, it might be OK for an office desktop but don't expect it to work reliably or anything silly like that...

PC reseller will generally also stock a premium brand such as Kingston which will cost 2-3 times the price.

They'll stock "generic" and decent RAM, yes, but I've never seen that much of a price difference. At least the retail prices seem to be ~30% higher - quite reasonable in my book - for name-brand quality RAM. Perhaps they mark up the "generic" stuff a revolting amount - nonetheless, the end price difference seems pretty reasonable.

 First
grade RAM usually comes with a lfetime warranty and will be RAM from Hynix (Hyundai), Toshiba, etc.

Indeed. Those prices I mentioned earlier were for Hyundai RAM. I've noticed "generic" RAM disappearing slowly from better PC retailers as well - no doubt for the same reasons you won't touch the stuff. Nonetheless, some people will always insist on buying the "$5 cheaper, 1/2 the quality" model :-(
