Cross·Spectrum - Galaxy CM-140 Sound Level Meter
I have not gone through them, yet. I was going to see if they could calibrate the mic I already bought from PE, and I think I need an SPL meter as well.

I know you said cheap. But how accurate is cheap?
I have no clue how to calibrate an SPL meter... So I am useless...

You can look into sound level calibrators...

and ebay...

If you use REW, you can use any calibrated mic for frequency, then use the calibrator to make sure your mic is dead on as far as SPL... (yeah, they are expensive, at least 200 bucks)
I use HOLM, and don't worry about measured SPL right now. I just measure the frequency response of each driver to check relative levels with same volume setting at crossover point... So I can't help you with true SPL response...
