FWIW, I ordered an oscilloscope from them a few weeks ago. Sent payment, then a couple days later, they said they forgot to charge me for shipping. Please send more money.
Well, by the time everything was added up, it was only a few measly dollars from the cost of a brand new unit from TEquipment. And with TEquipment, you get a full warranty -- the Rigol clearance units have no warranty. I politely asked for my money back.
I'll say this though; the lady at Rigol was very nice about everything and they were 100% courteous & understanding.
