Hero Armor, help plz

What would Primeval and Deldrimor armor remnants be worth these days? I assume the price would have gone up with the HoM requirements for GW2, or down with the event of market flooding. I have never really seen these items advertised either way so I am in the dark on this one, help would be appreciated.

Also, would it be more efficient to maybe put together a H/H team and just attempt to acquire the items yourself? Depending on the value of the two armor remnants vs time to completing a successful Slavers or DoA run for an inexperienced player. Any links on the subject would also be quite helpful.

deldrimor = 12-15k

primeval = 8k

deldrimor-10-15k
primeval-5-10k
