The low end Brothers are not bad machines. Because of the plastic parts they won't hold up well for heavy sewing or projects, but they pretty much all have assisted threading, easy to follow threading paths, quite a few stitches, and feet or other accessories are easy to find. Make sure that you have enough variation for stitch length.
The nice thing about the Brothers is you can just run down to Walmart and get going in minutes!
With basically the same set of criteria, I went with a mechanical (non computerized) Eversewn Sparrow. 15. I've been pretty happy with it so far, but it does seem noisy in comparison to the other machines at my sewing group, and if I was sewing on it more often, I'd want a faster machine.

I wanted a lightweight mechanical machine, the Charllotte model is also within your price range and offers a bit mor3.
