spectroscope woes

My class completed this flame test lab, but was unable to get any decent emission line spectra using the traditional spectroscope from flinn. Anyone have any ideas how we can get better data? Or know of an affordable slightly more advanced spectroscope? Thanks!

We had pretty good luck using some diffraction grating film and the kids cell phone cameras last year. Making the room dark enough was our biggest problem. I have also found this lab by Flinn that would probably work even better. Just Google Flinn Smartphone Spectroscopy
