The 4411 I have heard great things about. You can get it new for $139 on Amazon.
It's supposed to be the best (cheap) heavy duty non-commercial machine on the market. When I bought the Start my disposable income was very limited, that has changed but with the Start doing everything I need it to do for now there's no need to upgrade at this point.
Still getting my home "office"/work room put together after the move, put the sewing table (and old Ikea drafting table) up and unpacked the machine. Have to put my frock coat back together, finish a vest I've been working on and make my 1850s pants and/or maybe some fall front trousers.
Here's the last mid 1800s wool vest I made.
