I looked into buying a bag from evanp (the Rockbag), but I have a 'dola that is an unusual instrument... somewhat deeper than typical. I emailed him and asked if he would consider allowing me to return it (in pristine condition and immediately) if it did not fit, and he would not accommodate this request... so it put me off a bit, and I didn't pursue it. Still, it looks like the best low-cost option that I've been able to find when scanning, so I'm glad to hear that others have had good experiences with this seller and this bag.
