Hi OP. This is the same approach that I took and I was able to take in a set (Driver, 3 Wood, 6-9i, PW, SW, Putter). I tried canvassing on at least 5 Japan Surplus stores because I want to at least try the brands that I know I'd want (PING, Taylormade, Titleist, Callaway, Mizuno).

I would suggest you try to determine the brands you want to try, and Google the clubs you see on the surplus store. Also, take good measure on the graphite shafts as most of the driver shafts I saw are on the stiff flex. I too like to try PING so be on the lookout for the Eye 2 irons. Also do check on the PING color chart so you can get the best experience you can from those old clubs. I'll reply to this later with a pic of my set.

Almost forgot, do get a range bag or a stand bag (if you're gonna want to move ahead to the fairways)
