My search for a ST Prem just ended. While I was looking, I found that there were no NIB from distributors, some collectors had some, but bought them on spec, expecting to make a profit. Then there was the HUO crowd. HUO folks LOVE their machines and prices reflected that. Add to the HUO scene the mods that were done. I did not find ANY HUO that were still stock. Folks had modded them and the price reflected those loving upgrades.
So what did I do? JJ over at Game Exchange had a "Used" ST Premium on his website for a couple weeks now. It had been routed. I asked a ton of questions, bugged him relentlessly for pictures and in the end came to a price we both liked; shipped to my door. (Thank you JJ for putting up with me). It was more than a NIB ST Pro and definitely less than any ST Premium out there, NIB or HUO. I am putting a deposit down & he is now shopping it. The price was more than fair and reflected the history and condition of the game. However, I have always maintained that I am a player, not a collector. I like a machine with a bit of "character"
My experience has led me to believe that the NIB and HUO ST Premiums will hold their current value and possible increase until or unless Stern produces more. However if you are like me, the off route market may satisfy that itch for a premium.
