just make no confusion, my concern is not simply expenses or costeffective.. but they known as they have ""great support""
and looks like in your case it just didn't come true..
the 17 K is really ridiculous because that is more than a new spindle..
locally here a cabinetshop using a weeke, another has onsrud.. I see what those machines capable.. weeke has a huge head with many drill also toolchanger.. the onsrud has only
toolchanger..
by the way the biesse, if works, that really fast.. can run with 70 meter per min..
while this is not a perske spindle, still you could have one as a spare spindle..

heres a Colombo, still not 17K

another one
10hp Giordano Colombo RCE 110/22 ATC Spindle Motor
so after you paid 17 K still you have a used spindle...
