No one mentioned this, and I don't want to be a kill joy, but you might want to remind your 86yr old freind that copying the contents of the LP's to another medium, then selling the LP's is a violation of Copyright law. Once he sells the LP's he must destroy the "back ups" which is the CD's or digital coversions stored on the HDD. WIth that being said, transferring 2200+ LP's is a major undertaking and he will most likely go through at least two cartridges.
USB turntables are not built for sound quality but for ease of use. I doubt one would last thru 2200 LP's being transfered to a HDD. If you want a quality transfer, use a quality turntable / arm / cart / phono pream / sound card. Surely this will be a major undertaking no matter which path you choose. LP's to HDD is not an automated task. You will to monitor the job constantly to ensure there's no skipping, and unless you use a semi or fully-auto TT, you will have to be there to lift the arm at the end of the side which you will want to do becuase recording audio at cd quality to a hdd requires 10MB's per minute no matter if you are recording sound or the silence at the runout groove. I don't want to discourage you, but this will not be a quick and easy task.
