Sucker? I only bought one, but I could care less what it is worth 1 year from now. I just paid $8k for a STLE that the original owner paid $8k for 2 years ago. My LOTR is worth more than I paid and so is my other machines. If someone can get $10k for GBLE - good for them. Mine is not for sale at $10k. It will be the brightest and best looking machine in my gameroom.
If you sweat losing a couple of grand on a machine it is probably best to buy a virtual pinball with 20 games in it. The most you can lose is $100 per game at that point.
