Well that's unfortunate to hear about the wait time even with "quick" shipping. My BP's about 9 months old and growing fast, already looks cramped in the 30 gallon (I mean he almost never moves but still).
I've been keeping a close eye on Craigslist and Facebook Marketplace to see if I get lucky. But it's like, 70% glass tanks, 25% snake racks, and maybe 5% actual PVC-type enclosures, all of which are too small...
