Load Cell ADC HX711 Alternatives?

Question

Looking for an HX711 ADC alternative.  Sparkfun sells a pricey breakout board with the chip, but I cannot source the IC anywhere online for some reason ?‍♂️. Are there any ADCs out there that have a built-in instrumentation op-amp?
My current plan is to hook-up my load cell to a stand-alone instrumentation op-amp and funnel that into the ADC of my MCU. However, since my design requires 4x of this circuit, I would much rather free up some MCU cycles and off-load these duties to a dedicated IC. Any ideas?

You can do a parametric search at a distributor such as Digikey for various 24-bit ADCs that work down to DC. Expect to pay 10-100x more than the Avia part.
