Upgrading from Cricut

This is more aimed at professional folks I think, or small business from hobby printers.

My wife is hitting the limits and frustrations of using Cricut Explore 3 to cut her heat vinyl projects. Suddenly, they've released a new machine type and adjusted the software they use which makes her machine cut faster (yay) but now it's more sloppy and not cutting as well as it did (it's not the blade, I repeat, IT IS NOT THE BLADE!)

Her frustrations are becoming mine due to the earache. Does anyone on Tildes do heat transfer and normal vinyl work? She's also looking at printing to vinyl roll and cutting; her aim is mostly tees and teddies. Due to this, loading a full roll and having a lot of waste isn't ideal.

We're after advice and what her upgrade steps are. We looked at printing to film (DTF) and garment (DTF) options, but we are definitely going to stay with vinyl for now.

Thoughts, advice, options, anything of value to say is all welcome. Not to self promote or anything, but to give you ideas of what she makes Https://thunderlizard.co.uk/shop and look at near any item. You can see it is like 2x4", 8x8" and max usually 12x12" sizes and a mix of vinyl types from plain through to glitter. Hopefully seeing that should allow for better and more accurate advice.

Thanks all!
