Counting the color DMD, the price listed is very fair for a HUO BSD. But yeah, a very nice BSD like this is easily worth 4K if players BSDs are getting around 3K.

Are there BSDs that are worth 4200? Yes, certainly. A game in extremely good condition is worth a bit more than your average game. If you deny these things, you are just not trying to buy and sell games very often.

I looked for a nice BSD for years and gladly overpaid (according to you) for it. You want to buy mine for what I paid for it 3 years ago? Apparently not since the only reason I paid what I did was to try and accomplish some price pumping... whatever the hell that means.

People pay whatever they want. If a barcade pays crazy money for an arcade (like a Tapper for 3 grand), are they price pumping that game? Of course not. If supply and demand = price pumping then I agree with you.

Is your definition of price pumping just blindly saying a game is worth more just to attempt to sell it for more money? It doesn't really work that way.
Are you implying that a game that people say is better than it really is will increase the price of that title?
That could be true over a short period of time but eventually knowledgeable pinball people will reveal the truth of how much replay value there really is after ownership.

See here, I sold a Slugfest for 2800. Are all of them immediately worth that much? No way. Is a HUO one with a Bally distributor's receipt of sale worth that much? Probably so, and I know a few people that would likely pay more for it. Will that incrementally make all Slugfest's immediately go up $50? I don't think so. Things go up because as time ticks along, those items get harder to find in good condition and people end up paying more for those items. It's quite simple.

Specifically in the pinball world, when a repro play field is announced, that game sees a small increase in demand, but when that play field is actually released and you can buy one, the game really sees a surge in demand and that in turn makes the price go up very quickly. It trails off once those restored games hit the market and as time ticks on, sometimes the price creeps back down close to where it was before that particular play field was announced.

It doesn't matter if you own a BSD. The above examples hold true for ANY PINBALL TITLE. Price pumping must be the term people use that do not understand the dynamics of a collectible market over a given period of time.

One other fact. A routed and unshoped BSD listed for 2650 in the Pinside marketplace yesterday, sold in about 30 minutes. I feel that any decent BSD listed for 3k on Pinside would sell in a day or less. That's just the market demand for the title.
