   Plenty of "hobby" machines do have DROs.  Just ask anybody who is using   
   a high price "pro" machine that belongs to their boss's bank.  LOL  They   
   will tell you all those import machines are hobby junk.   
      
   DROs are fairly cheap, and available for almost anything these days, but   
   many of the "better" prosumer/hobby importers offer preinstalled DROs as   
   an option.   
      
   There are even modestly priced DROs with bluetooth interface for a   
   tablet or maybe a cell phone.  I'm not sure there.  I like my DRO   
   hanging off of a big heavy steel arm.
