Check the difference between the LPRO and PRS-10 on John Miles' page:

Assuming these plots are representative of what you are likely to get from
eBay parts (a pretty big assumption right there), the main advantage of the
PRS-10 seems to be at high tau, where the performance of a GPSDRb is mostly
driven by the GPS and PLL anyhow.
