I am purchasing my very first serger and don’t know what could be a good one. I bought a Consew last week and found out that they used to make only industrial machines, so I guess it’s a good one. But I found out that Elna is even better. I found one Elna 744 on sale for $749.99, can anyone tell me if that’s a good price? I found on the internet the Consew that I bought last week for $200.00 less. I want a good machine, but want to pay what is right for it.
