3D printer sale options


Hello all,

I’ve been asked by my workplace to find suitable 3D printing options for rapid prototyping here in the office, I’ve selected a few FDM style 3D printers. My problem is we already have a nine year old OBJET 30 3D printer from Stratasys with about 4000 hours of printing and in good maintenance, the print heads however are no longer functioning and the cost of repair with extending warranty and an onsite engineer was quoted at 3300euro. we are looking at obtaining a new updated FDM printer and I am wondering what to do with the old one, would it be of more benefit to repair the printer and sell it on after repairs or to sell it as is; in need of repairs. Ive looked online for second hand OBJET 30’s for sale to judge the market but the value seems to drastically fluctuate, so I asking you the 3D printing community to point me in the right direction. All help and comment’s greatly appreciated thank you
