Thanks for all the advice, I went with a bit of a compromise. I needed a new SG so I bought one for $525,000 who's transfer price estimate says he's worth 750,000 to 1,800,000. I put him up for auction at 1,300,000 because if anyone actually buys him for that I'll be happy, and if not I'll keep him as my starting SG and sell the other one before Monday :)
