Thats about 14 dollars more than an op-amp and it doesn't give you the full flexibility of the 50 cent op amp.
I would get a couple of LM324's to mess around with on some breadboard or strip board - in fact, thats what I am doing right now, some are configured as schmitt triggers, others as audio filters.
Its quick and easy unless I am missing something very specific to your application ?
Well strain-guages were mentioned, so a common-or-garden opamp is unlikely to have anything like the CMRR needed.
What is required is/are instrumentation amplifiers.
