For the larger size of lathe, ones that use the BXA size of toolholder, if you are lucky, you can pick up professional parting off systems off ebay.
I picked this type up for about 25 UK pounds ($35) each. One left, one right handed, and I bought all shapes and widths of tips for 2 pounds each
The advantage with this type, they can also be used for long reach left and right hand turning as well, as you can pick up a full range of different tips for them. I am also starting to pick up other holders as well, that all use the same tips. My latest one is for plunging into the end of a bar, for doing recesses.
This is how I part off with them.

And this is how the manufacturers show how to use them, and it is well worth watching to the end.

Even though mainly designed for CNC work, they are perfectly happy working under manual operation as well. So don't discount them as not fit for purpose just because they are used mainly on high speed machinery.
My holders have allowed me to turn (no pun intended) a lot of those difficult jobs into easy ones.
