Solidoodle 3 for $699 or Solidoodle 4 for $999?

Yes it's always surprising to see a delta printer doing a print !
It's right that the print made by a delta printer is more regular(and more precise with a 0,02 mm X/Y resolution(SD printer have only 0,1 mm)), but also faster(3 to 6 time faster than a SD2).
But it's a kit so you have to build it .

whats stopping the SD from getting higher resolution? the software? or the threaded rod? ultimakers are made similarly and they can get 20 micron layer height too

I'm not talking about the layers height resolution, quite all the printers can make 0,1 mm 0,2mm and 0,3 mm height(0,2mm is 200 micron and not 20 micron !)
I'm talking about the X/Y resolution not Z, it means how much precision the horizontal moves of the head have.
Of course the SD2(or 3) as many others can make layers that have 0,2 mm height and even 0,1 mm.
But it's horizontal resolution(X/Y moves) is 100 micron and the rostock max is 20 micron( I think it's because of the delta system).
