Yeah I like Imitation myself...I have also used Office Depot brand with no problems. I'd say that CD Burning is pretty good so I'd say a lot of brands should be ok. The only brand I've had problems with has been Maxell.
They have free shipping offers pretty often, and when they do, I like to pick up those 100-packs for $16.99 or so. They've worked well for me. 100 Jewel Cases usually costs about $14.00, but usually at least 4-5 show up cracked.
just dont get the ones with the cheap silver backing. A white or colored printed surface is best. I once lost a years worth of audio to cheap silver cds. They scratch very easily when they get old.
