Something 2nd hand? Most comments on here about PF30 seem to suggest they’re dumping their Cranks & going back to std BB/adapters. I bought an inexpensive dual ring PF30 SRAM 1400 crankset (Unused OEM of ebay) a while back to replace a E-13 TRS single ring setup, as it was cheaper than buying a dual ring spider for the E-13. I did hear that the SRAM (x9) stuff is becoming more expensive as you can dump the spider & fit direct chainrings (iirc)
..and in a classic STW move.. Are a set of scuffed E-13’s of any interest to you? (Does use a proprietary BB but now they come with a 12mnth warranty)
