I personally would not get a machine with a 4x4 hoop - once you start embroidering, you will want a 5x7 hoop.... Everyone I have known that started off with a 4x4 hoop quickly decided that they wanted the 5x7 one and the 4x4 hooped machines do not have a high resale value at all... not to mention the sewing field is small so your labels will always be very small. A 5x7 hoop will allow for more possibilities and you won't regret the extra money put in to it for that extra ability you will have - you'll start to look at things everywhere and envision designs on them lol. I know I did.
Just my opinion on machines - there is just so much more you can do with the 5x7 hoop that the 4x4 just won't allow.
Brother makes an economical 5x7 machine - just get the one that allows you to use a usb stick to transfer your designs from your computer.
