Check Amazon for QIDI they have their new stuff out there now at a good price. I have heard it is decent.
I just did a print yesterday in the last of the original QIDI orange that came with a printer a year ago or so and it printed fine. I was a bit surprised it held up that long.

Also Hatchbox (make sure it is an authorized seller) and eSun are good. eSuns PLA+ is great stuff.
