No worries, Piper.
I'm sure others will chime in with first-hand experience. But from the recordings I've heard online, the BSC1s seem to provide excellent value, i.e. good quality at a low price. In their price range, I think they're tough to beat -- especially if one has an interest in experimenting with different patterns (they come with omni, subcardioid, cardioid, and hypercardioid).
For an even smaller budget, there's also the Avant CK-1s, which come with omni, cardioid, and hypercardioid for a whopping $300/pr. I've used these once or twice and also felt they were a good value.
For what type of recording will your brother use the mics?
With what other gear?
