I don't feel any of my purchases were stupid, and many I paid over normal market value for. My purchases have all been well thought out. With that said, my lemon pastel Winston was $800 when I purchased him in 2006. I've been offered $1500 to $2000 for him since then over the years - once while sitting on the BP.net table in Daytona.
I don't care about "deals". I only care about the animal, and I'm extremely picky about the looks of my animals - so I'm willing to pay more for them.
