That's crazy Loud as I was just checking the selection on testers there too after I seen your comment under the engine section..... had a stem tester I bought there (first tool I bought) in 1981 for my 650 mercury synch second if I remember right..... both finally gave up ........ Adware didn't pop up for me but I agree its a very bad idea on there part ..... and yah they are going outta business been reading it for a while now.
I always bought (mostly anyway) Craftsman tools, Kenmore fridge, washer etc and had a credit card for years that the wife and I over used ......always thought the huge catalog you would get in the 50s and 60s was so cool.... best friend and I dreamed of searching in it for treasure with scuba equipment they had listed from age 10 to well in our teens ..... he even joined the Navy and passed the first test to become a seal but then decided to not go farther as he just got married. Even bought a pool table from em when my wife and I first got married but had to cancel after I came to my senses and figured I couldn't fit it in my 2 room apartment on the second floor with a tight turn through the hall way. LOL.
Ha this got me a think in of a calculator I bought way back in 74 or so there called the m8 that was one of the earliest hand held ones ....... won't tell you how much I paid but its only worth around 16 to 20 bucks on Ebay. Ok a hint its gotta go up at least triple to brake even.
