When buying stuff from a vendor, if the sale "goes right" it doesn't matter if the vendor is any good or not. The real testis what happens when things go wrong!
So I bought this AMC T150, OD, bell, flywheel, plate, yoke from American Parts Depot. They're on the Least Coast, I'm on the Left Coast, so shipping is ouch. Probably $125, truck freight.
So I called up Doug (this is the last work day before Christmas -- of course) left a message, expecting some sort of stress -- nope. A simple clerical error, didn't check "USED PARTS" on the paperwork. Another week went buy for the shipper (Overnight) to "research" it. Eventually it went for the USED price. Whew!
APD didn't freak out (I admit I did), didn't blame me, didn't blame Overnight, didn't blame anyone, they just checked it out, worked at it, solved it. Clearly I'll be ordering from them again.
