I am reaching a point where I want to get rid of some of my maxed Plasmas, switching them out for mining (presumably maxed VL toxics) - so my question is:

What does a C 17xRes Plasma go for nowadays?
and
What does a VL 16xMin Toxic go for nowadays? (here, would be interested to know both for alerting a unnoc toxic and for them providing it, and whether there is any price difference here) This would be in bulk, buying some 10 or so (offers, i suppose are welcome, but won't take any until I sell the plasmas).

plasmas are 1.2-1.5k ctp, toxics are 400-600ctp but if you need credits you do not need switch plasmas for toxics because you can convert research points for credits

^This.

Remove all defenses from your plasmas and just make them pure production. That way they produce more and if they get taken it's no big deal since they become easy to replace.
