Sorry, no I wasn’t going to buy refurbished, just that brand and tower type that interested me, sorry for being vague. I’m going with the other you recommended in the first link. The other information is really interesting and informative. I’ll buy the cheap one for now (6T), and save up for the expensive one. I really need two anyway, one on site and one off site. Thank you for taking the time and explaining. Bullet proof sounds awesome!
