I missed out on Too Many Salty Swift..., but I did pick up some nice stuff there including Myra Melford's Even the Sounds Shine and Theo Jorgensmann's To Ornette - Hybrid Identity for $7.98 each. Great prices, but be prepared for a challenging search through their lists to find the stuff you want.
I just devote some time every few weeks to searching 'jazz' by genre, making sure to check CDs so it doesn't get cluttered with DVDs. It usually turns up around 500 items. You can also search by label. Oh, and I've discovered that the Cecil Taylor set only goes for 14.98 at JazzLoft, half what most outlets who do stock it are asking.
