Have both variants from last week, looking for a FouFoune or Lou Pepe would also be interested in similar sours. Am located in Somerville, wouldn't be opposed to driving a little to get it down though.
Just FYI, 2:1 isn’t even $4$ for significantly limited seasonal lambic. Perhaps you just need the right set of eyes, but you’d probably need to get lucky with an international trader. Kriek, Rose, or Classic Gueuze would probably be a closer ISO
