I'm not a collector, so I wouldn't pay that. I paid $850 delivered for my 7x57, but I did pretty much luck into it. I had an RSI in .243 at the time that had a much nicer stock; I swapped the stocks and sold the .243. That said, if I were trying to fill out a collection and had the resources to do so without strain, I'd jump on a grail gun when I found it.
If I find a deal on a 6.5x55, I'd have to consider it, even though the pressure is off now that I have the 7x57. I'm not on a quest, but still have my eyes open.
