First of all I think your hoop sizes are 4x4 and 5x7, you take the inside measurments and these are the normal ones in this area. I myself could not limit myself to this small, I rarely use either one of these. If I have smaller designs I normally use a larger hoop and do multiple ones in one hooping. Some designs can be split if you have the correct software and some come with a split option. I went for the largest that I could afford when I got my first one and that was really big and a yr later when I had the opportunity to get the largest hoop at a great deal I traded my Viking Ruby in for the Viking Diamond Deluxe. I agree the hoop size is the first thing you should have looked at. Hopefully if you got it from a dealer you got good customer service, another thing that's worth its weight in gold. There are some on here that do fine with these two sizes and others like my self who would feel limited. You have to decide for yourself what you would be comfortable. You can check on trade-in values and specials to see if that would be an option without costing you an arm and a leg. Make sure first that you are going to like emb first before you worry about the size. I had never emb myself when I got mine but know myself well enough to know I'd have felt cheated if I had too many limitations on it. Good luck.
