About 20 years ago I purchased a Weider Megagym, it cost over $1000 (on credit card of course). It was a wonderful complete and expensive home gym. I had to put it together and while I am usually good at that kind of thing, this was tremendously difficult. There were bags and bags of parts, and parts missing.
I finally gave up, we gave it away. What a huge waste of money.Took me a while to pay for something that I never used and didn't even have anymore. So that is my big regret and expensive regret.
