Illusion is a bit of a hard sell, and casting isn't super popular with memsers that I've seen since they have fast cast - but would think 100k 30-40e... getting hard to sell anything tho, could end up lower
I agree with yoda, 20/20-s are still pretty rare, but they've dropped in price A LOT. Its also an illusion staff, hard to sell, so 75-100k sounds more realistic than 100k+xx...
Never knew what people see in these but they are still pretty rare and the mods are nice, although it's a mesmer item I'd say it can still get 100k+5e at least.
