I went to all four hardware stores in town today: Menard's, Lowe's, Home Depot, and Ace. None stock 50 amp subpanels. I see 50 amp RV panels and hot tub panels, but those aren't really the right things. I really only see 70 amp subpanels like this:

I assume that if I were to use something like this, I'd have to have a 70-amp breaker in the main panel and it might change the wiring requirements to the subpanel.
