My hesitation with limited editions: Before I'd spend (relatively) big money on one, I'd like to know that parts will be available in 10 or 20 years and that serviceability will be practical in the future as well.
FWIW, that's why I bought my Sumo instead of an MM300. I've already dinged it hard enough that it required regulation afterward. I'm tough on my watches and I'm a DIYer. I generally buy based on that.
