Some good thoughts Pat. I'm bored at work, so what the heck, I'll throw out a reply to this one too.
I'd say the coin ops hold their value well assuming you didn't overpay in the first place. I paid $500 for mine, and i could probably get that much now easily if I were to sell it - so it's held it's value pretty well. I guess I wasn't commenting based on resale value though. I've played on home models, and I always thought, and was told, that the coin ops just plain play better and last longer. If that's the case, why would pay more for a home model than you can get a coin op for. There's 5 coin-ops for sale in my area right now (all by the same seller though) for $425 each.
edit: also wanted to say, no offense meant to the seller of this table. The OP posted on here asking for advice. I was in the same boat a little over a year ago, and if it weren't for the advice I got on here, I would have ended up buying a home model instead of holding out for the coin op. If the OP has no intentions on playing tournys, maybe this table would be good at the right price.
