One thing I will say for Lenovo, and at least historically HP - probably other brands too, but clearly not all: if you have possession of a unit with a serial number that shows it's still under warranty, they couldn't care less where/how/when you took possession of it, they honor the warranty. By definition, if you bought a black market product, the serial number will not be shown in their database as under warranty. I almost always by lightly used gear just to get great stuff for as little as 50% of the price of new, but if it's a significant investment, I won't buy it without getting the serial number and checking the warranty status myself. When a seller on, say, eBay, won't provide the info, that's reason enough not to deal with them! Glad it worked out, for the most part, in the end Brian.
