One thing I forgot to mention is that even though the stuff I bought was used, older, and has been superseded by more recent models, I did some research and the current models of the stuff I bought are *not* any better in terms of capabilities, they just do what they do faster (1-2 seconds instead of 2-5 seconds for the stuff I bought) and have prettier LCD displays. The significant stats, such as how much mass capacity they have and how accurately they measure that mass (these are mostly all digital balances) are the same for the older equipment I bought and current model line equipment. Having said that, I got all this stuff for 5 cents on the dollar compared to new prices of the replacement models today. I got 6 digital scales, one lab shaker, and 9 calibrated weight sets. New prices for all of them would exceed $40,000. I paid $1,500. Auctions fucking rock! I actually don’t need 6 digital balances, nor 9 weight sets. I plan on selling 4 of the balances paired with 4 weight sets on EBay. I’m hoping to get my entire investment back that way, making my two balances and lab shaker free.
