I try to go to industrial auctions when they happen to be near by and I have the time. Like you said its amazing what people (scrappers I mean) will go crazy for and run the bidding up on. Same can go for the deals too though. I bought 5 industrial printers at the last auction I went to for $2 each, and listed them on an industrial auction site as non working for parts. Final price I got was $1500 for the lot plus shipping. Wish I could do that every day!
