Mario, I think we are in the same ballpark and just suggesting different marketing strategies. My initial thought - due to how nice the kit looks (and I am guessing sounds) - was $1400, but then I had to remind myself that the shells were not born together, and the hardware isn't all original, etc. If I were listing it to really sell (and we're talking Ebay strategy here, which is hypothetical as I believe the OP is wisely holding onto this cool kit), I would start with a "too good to pass up" starting bid of something like $850, and then have a BIN for $1250 (if this were too tempting, then ramp it up to $1450). There is a good chance that those looking for a good deal will start the bidding, worried that someone will find the BIN reasonable. Then you hope that others will start in the bidding and become "invested" in the item. It could potentially go for more than the original BIN, which is by that point moot.
I do get the other strategy of putting a higher BIN price with the chance for a "best offer." I think those who do this figure that every once-in-a-while you will have someone pounce on the high price (which must happen). Saying this, the high price may chase people away who would offer a reasonable amount for the item.
There are so many ways to market effectively. I tend to like sellers who consistently offer good quality, honest merchandise for reasonable prices. They build up a loyal clientele.
