I've got a Juki TL 2010 and I use Schmetz Quilting needles that I get bulk on Amazon, you can also use universal needles. The last time I bought needles I paid roughly $65 for 100 but when you think about the cost of fabric, batting, and thread, a few bucks worth of needles per quilt isn't much at all.
I've also used Schmetz Universals, last box I bought I got 100 for $31 and they worked fine. Imho it's more important to change the needle regularly than to overthink about what type, I didn't know about changing the needles when I first started sewing, I thought you only did that when it broke, it was revelation when someone told me to get a new needle!
