If you bought a car in Colorado
@MissEmmy and moved to California would you feel it was necessary to return to Colorado every time it needs any service? Hopefully, no. If your machine dealer has a service department that services other brands then they will be happy to service your machine. They do make money from servicing the machines. They also sell you needles and other doodads while you are there.
I took a quick look at the Vibrant. It didn't interest me. I wouldn't buy it if it was cheaper. It has knobs on the front. For me those are knuckle bruisers so it's an immediate no. I wanted all dials and bought accordingly.
Now, some dealers throw in extras such as classes, a discount on accessories for it for a year, or a free servicing at one year. On sewing machines anyway, not sure about serger/overlock machines. I'd call and ask. That could sway you. In either case ask how much servicing will cost you.
I've had mine for 18 years. I'm not a heavy user, actually not the last few years at all. But it has never needed servicing. The blades are still sharp. It still purrs. I change the needles more than some people who apparently never change their serger needles. I also cleaned it really well after each garment and midway when I was sewing fleece. The only time any of my friends have had a serger in for service it was the air threading had stopped working or they foolishly damaged the cutting blades by sewing over pins. You pin differently with a serger or use those clips so it's easy to see them to remove.
