I didn't actually buy them to sell for profit . Most I bought pre 2002, when prices were nothing like where they are now. So, yes I would be upset if I lost money . Back then I paid $950 for WH20, and either $800 or $1000 at retail for my ES, and $1700 for a TZ. If I lost money on these because the price dropped below what I paid I would be pissed. Mainly because I wasn't smart enough to see the decline and sell while I could still make a little on it and thin down my collection .
Now, I buy old beaters that are good titles , knowing if I put a hundred hours into a restore , and all new repro parts I can sell it for more than I have in it ,if a financial disaster strikes my life.
Only NIB I bought was bought simply because I liked the game , and wanted to experience the opening the box excitement , which cost me a thousand bucks of instant depreciation for that joyous moment . Only did that after 23 years of buying beaters and fixing up , and used the profit from white water to afford it .
I think it is a FUN way to spend my money . And if I come out with some profit I'll be happy , can't see me loosing money on my TZ at the very least .
