I get really lucky when "browsing/ lurking" around Adorama's used section. Found a like new V860II for a steal!
Now i need to figure out a snoot/grid situation for my speed light, i will poke around in the flash sub-forum as well.
Have a look at the Magmod stuff, it's super overpriced but the quality is good and the ease of use in the filed it where the value is. It's very quick to change out modifiers like grids and gels.
