Recommendations for… Sewing Machines Parts and Sales in Los Angeles

Soo I am new here and I looked at the sidebar and Idk maybe I didn’t look in the right places, but I was hoping for recommendations on where/what brand to buy of certain things.

Right now I’m looking mostly at getting a serger. Through google I found some recommendations for good, budget-friendly ones, but I wanted to know which machines you guys liked.

I’m also looking to buy a dressmaker’s dummy sometime in the future (probably later this year or, hell maybe even before getting the serger). I was wondering where you guys would recommend I look.

Thanks! And sorry if this is not like, the right way to ask
