Any sewing people's from Bangkok in r/sewing? Sewing Machines Parts and Sales in Los Angeles

We will be back in Bangkok in a week and I am hoping to have a look at some industrial sewing machines to buy. I know there are great fabric markets and I plan on visiting those as well(if you know the best places for heavy duty textiles and tech fabrics that would be sweet as well) but more importantly I am in search of a new needle feed industrial unit. Any pointers on somewhere to loom would be greatly appreciated.
