new spinner needs some advice

[stringcat]

This is my first post. I've been getting so much info here and everyone is so friendly!

I've never tried spinning before and I'd really like to. Can anyone recommend a drop spindle that you like and where is a good place to buy it from?

Also how many yards of worsted yarn can you get out of an ounce?

Is there anything else I should get besides a spindle and roving?

Thanks for any help you can give me!
