$1500 is a very high price tag for a luncheon. However, if the remark is on one of his rare convention variants and is a legit character, I feel it could be worth it.
I am a big JSC fan and I certainly dont feel alienated by the price tag. It could be the only time I would ever get to sit down and hang out with my favorite artist. If I can generate the funds, I will probably do it.
