I agree. My problem is that a lot of the vinyl I get is limited, so rather than save up for a nice record player, I end up getting the vinyl. I own over 1,000 vinyl (most of them old 7"'s) and I really need to play them on something better than a shitty Crosley. Every summer, me and my friends have a party and myself and another mate DJ. He brings a duo set of Technics he got in 2000 and I get a pang of jealousy every time I use it...
As for expense, put it this way - earlier this summer I got a limited edition single sided 12" vinyl of
"Boris" by Boris - only 100 copies exist in the world on red vinyl. The record was about £20, but including postage and customs, it set me back over £50 - all for one 8 1/2 minute song...which I still haven't played.
As for me, as much as I want the full set, I can't see myself playing them that often, so I might go for the CD and 2LP edition to compliment the Data Discs SI&II like you. I love vinyl, but it's not the most user friendly of formats. Anything above 2 discs is a pain in the arse.
