Appraisal advise please - Cheyenne Hawk Spirit and PU2 power supply

Hi guys i have a 6month old spirit, inc. 25mm grip, cheyenne PU2 power pack, running as new. black drive and grip.
I am about to put it up on ebay/here too, i have my price in mind, wanna see if what you guys feel i could get for her.
I ab love her, great bit of kit, just not loving the cartridges, yadda yadda yadda, and have since fallen back in love with my mickey sharpz.
I will be getting either a dragonfly, or pos. the new inkjecta flite when it comes out? love rotarys and love the fact they made me fall back in love with all my machines again- become a machine geek since researching rotarties

Cheers Adam

60-80% of cost when new is the basic way to price a machine

I agree, if there are no physical signs of wear 80% is fair. If it shows how much it has been used then maybe closer to 60%. I assume the spirit, power supply, grip, pedal and all cables is about 900$ new. So I would say 600-700$ is probably a good target.

the good thing about tattoo machines is that they hold value no matter if you're the 1st owner or the 10th. Unlike other thngs we invest in.

thank you so much, makes alot of sense, appreciated, doesn't scare me now to buy and try machines with a small diminishment if i don't get on with a machine
