The Pi 2's I had were hit or miss and had hardware issues, and ended up repurposing an old laptop to fill in for it. Worked fine, and had decent luck buying older laptops off of kijiji / craigslist / fb marketplace and using those in lieu of Pi's. Outside of GPIO that's on the Pi's, the laptops are fine, and though a little more expensive they can also run more powerful VMs, have cooling, and can do x86 stuff.
