Ah but a sewing machine is a one off purchase isn't it? Unless it's your third...like mine is
It might be an option if I ever get good enough to make my own clothes etc but for now, coats moon does the job and is a step up from the cheap rubbish I used on my last machine.
Using expensive bits and bobs needs to be justified.
Very politely - I have to totally disagree with you. You make a really quality finished product by use of quality ingredients, not a hugely expensive bit of kit.
Use a cooking analogy (seeing as cookers and recipes seem topical on the forum right now) - you can make a glorious meal in very basic good quality pans IF you use great ingredients. But no amount of fancy pans or kitchen kit will turn second rate ingredients into a great meal.
You can make wonderful stitched items on basic machines if you use wonderful materials, and that would include good design and great thread, zips whatever.
The very expensive machine is the last bit of kit to buy, not the first, and won't make a silk purse from a sows ear.
Too many people have been sucked into the "buy this expensive machine and you'll be able to make better stuff" rabbit hole I think. And then speak - even here - about how they don't use all the fancy functions, prefer their simpler and smaller machines, and are going to sell the white elephant.
But enjoy - I hope you get it sorted and working just as you want it.
