You might look at refurbished machines. Many times, this are just open box/customer returns and have been serviced and are like new. I purchased both of mine refurbished and they have been great. I have Brothers but I hear Janome is a good brand, also. Here are a couple of good stores: Allbrands.com; KensSewingCenter.com I have bought 4 machines from Ken's Sewing. Not affiliated in any way, BTW!!
Also, if you can afford it, do go for at least the 5x7 hoop size.
