I'm so glad I found this forum. I have learned more then I ever thought possible about nozzles :-)
This is the second year we have been making snow here, we only get about 10 days a year when it is cold enough down here. Has anyone used an oscillator with their gun? We might get one for next year- not sure if we want to spend the extra 80 for it?

Welcome! I'm always happy to see more southerners!

If you can get it working maintenance free, an oscillator is a fantastic addition. You get a more even distribution than you would get just moving the gun by hand.

Check out this video from tominwi that has his fantastic oscillating setup. If you search through the archives for oscillating, you'll see some great posts from the various memebers that have made one.
