Can be had much cheaper, especially if OK with a non-zero failure rate (and/or bit more latency). Note that my hands-on experience with this stuff is now relatively dated, from a "prior career" -- coming up on 10 years now, even. If anything though, then I'd guess that it's become cheaper over time, not more expensive.
