I used to have 2 brother punchcard knitting machines, ribbers, the lot. 70s, 80s, 90s but they did take up a lot of room and needed a lot of dexterity. I must have got the outlay back but eventually decided that the output was not worth the space, they became dust gatherers, so I gave them to a rehab centre, hoping that they could use them for some sort of income
I hand knit a great deal and my hands are becoming iffy now but circular needles are the way forward, two circulars, they are flexible so knitting sits in the lap. Knitting for a while plus breaks, makes arthritis manageable as do special crafting fingerless gloves with thumb supports
Chiaogoo make fantastic interchangeable kits, needle sizes and lengths, all in one small zipped bag and the metal lace needles are very easy on the hands. Purlescence is where I got my kits from
Learning another knitting style really does help, it changes the knitting action so is equivalent to hand resting
