I don't know about the acufil system but just about all emb machines should be able to quilt in the hoop, depending on how large the hoop is. I have the Viking Diamond Deluxe and previously had the Ruby and also the Viking +1, I love my machine and it has one of the largest hoops around. I have nothing bad to say about Jamone and I know there are lots who love their machines as with all brands. I'd suggest to search around to see what's in your area but also know you need good support from your store, that is key. Most stores that sell gently used machines offer some kind of warranty along with classes. Good luck on your search. You can find really great prices on the newer slightly used models though
