It all depends on what you want to do and what you consider inexpensive. You can get a pretty bottom of the line Brother from a box from Walmart and be up and sewing within minutes, and still have a threading assist, straight/zigzag, and multiple other options. They won't hold up to years of heavy every day sewing, but will last out 3-12 months just fine!
For a portable class machine, I chose a mechanical Eversewn Sparrow as non-computerized but with options and reasonable light weight, plus reasonable cost, biggest drawback is it is not a speed racer
It's doing pretty good for me -- my Bernina died and I need to get a new main machine myself. I'm looking at a Juki straight stitch as being perfect for me 99% of the time. For my main machine I have a flush mounted adjustable sewing table and I really want a top drop down bobbin.
