NIB without a doubt. You get a full warranty.....everything "should be perfect".....shipped to your door (so many on here don't understand that the NIB price includes shipping so then they sell it after playing it for a year or so for $500 less they truly think they are given the next guy such a great deal....difference is someone has to pick it up and many on here drive hours round trip). Your first $300 loss (shipping) really isn't a loss on the "use of the machine"......it is a loss on the shipping you paid to have it put on your driveway and not have to drive anywhere....
However, if HUO's are priced correctly (which I agree is 10-15 percent off the price PRIOR to shipping) I buy HUO (bought a MET PRO HUO ($3,700), TSPP HUO ($4,100), X-MEN LE HUO ($5.2K with shaker delivered to my house), SM HUO ($5K but perfect), IM HUO ($6K with $500 in mods but I knew I was overpaying but it was delivered and the guy I knew and even put in 2 shakers for me).
As an example use AC/DC premium a $6.3 K pin delivered to your house (mine was $6K delivered). You have to take out the shipping which makes it a $6K pin and subtract 10% that gives you $5.4K. That is with only a 10% loss (which many "cry" about....my response is get out of the hobby if you can't handle a 10% loss you shouldn't be buying a $6.3K pin in my opinion).....these are expensive items so people have to understand 10-15 percent of a big number less the shipping cost is a DECENT LOSS (maybe some people shouldn't be in the hobby if they can't afford that type of loss....everyone wants the hobby to be free or almost free). I think buyers are finally waking up (really it is the buyers that make a market) and finally "digging in a little" and saying "wait a second" and unless it is priced correctly they aren't buying (10% less as well as $300 less for the shipping....).
Therefore, I DEFINITELY will always go HUO if priced correctly.....but would buy a NIB if the prices are the same or very close to an HUO. All you have to do is look at all the AC/DC HUO premiums "sitting" and the ones selling are following the 10%-15% rule after subtracting out $300 for shipping cost. Hopefully, this becomes the "new normal" as that will make people think twice about pre-ordering NIB and help keep NIB prices more in check and might stop LE's selling out the first day or two (well, that will probably not happen UNTIL THEY START MAKING THE DEPOSIT NON-REFUNDABLE which I truly hope happens.....people are always hoping for the next TRON LE or BIBLE without taking the risk (one reason I think you see cancellations when certain pins don't prove to be as popular).
