Is it actually impossible to find a Di2 group at this point?

[username]

I hate to post something on-thread, but I'm seriously wondering if it's just impossible to buy a Di2 group at this point? Ultegra, Dura Ace, whatever: they all seem to have fallen victim to the Great Biking Boom of 2021. Am I missing some obvious place that has groups in stock? Is there some way to cobble together a group from several reliable places? Take my money! I feel like capitalism has failed me. Sigh.
