So for this customer gig I need to measure the actual acceleration of a parallel-rod transmission line that's being pounded into the ground with a built-in slide hammer. (It's for measuring soil moisture and salinity by TDR.)
We're thinking about putting the TDR pulser and sampler in the part that gets pounded (in a potted module obviously), so knowing how bad the acceleration gets is going to be important. I expect that it'll be several hundred g in volcanic soil, so a full-scale range of 1000-2000 g would be about right.
None of the MEMS IC accelerometers go anywhere near that high. Measurement Specialties makes them, but they're $160 in onesies, e.g.

Anybody used them?
