I have what I think is a good deal (250$) on a Babylock Ellageo ESG3 but it does not have the hoops. The machine was used for quilting and is it beautiful condition. I am just confused on what hoops would work with it. Does anyone have this machine and know what hoop numbers I should look for? Thank you!

I typed in your brand and model and came up with a site called All Stitch sewing supplies and they have the hoops and part numbers for 4 different sizes each one quite cheap. You don't say what country you are in so freight might be an issue if you are not in the USA.
Worth you having a look.

When you order hoops they usually tell you what machines they will fit. Also in your manual it should tell you the item number of the hoop.
