for resin there is www.madesolid.com. they are at $100 a liter. if their resin is as good as their pet+ filament then you can make out really good with that. also check out the solidator sla printer. http://www.solidator.com/3D-Printer.html. i dont know if its better or worse than the form1 and others. just giving you another option. it uses a dlp instead of a laser. the build volume is gigantic and it does a whole layer in 1 shot so its supposed to be faster.
