Careful with 'anno on a budget', if they screw up the tolerances ..........pain is endured.
Really the only place left to go is DC, JMJ is done. I am not sure there is anyone else out there with their CNC codes to do an excal in any other flavorings.
My fav millings are featherlight swirl, HL and streamline.
at this point the only 'new' custom would appear to be DC with the options beyond that, tray, fsp, etc and $o forth.
