what tactics do you use when you are looking at buying a domain either from someone or ootb (out of the basket) or dropped etc
I am interested in how others buy names to profit from them to see just how we all vary.

have you already an end user in mind ?
do you go by estibot or valuate ?
do you get a pro appraisal ?
do you look at cpc ?
do you look at searches ?
do you check google insights ?
do you check past sales ?
do you follow recent trends ?

or something else ?
