As long as you don't get one that claims to make bread too fast, you should be good. There are lots of super expensive fancy machines out there, but I would think you don't need all the bells and whistles.
I had a terrible experience with West Bend's Just for dinner breadmaker (it's a small machine, since there's just me and my hubby, I thought that would be great), because it tries to make the bread too quickly, namely in 45 minutes. The yeast doesn't have time to work out and the bread tastes really yeasty (not to mention, to have the bread risen enough, you have to use like 3 times the yeast you'd otherwise put in bread).
I have an Oster Breadmaker model 5838 (another low cost brand) and I find it OK. The bread is tasty Especially the 100% whole wheat that my husband adores (well, he doesn't have IBS, thankfully). It saves a lot of time and effort, and you don't have to do cleanup either. That's the best thing, my kitchen is not all flour after I have made bread, LOL.
