Yup, if you can't find an SA, what you want is a GL: https://www.ebay.com/itm/DENON-DL-10...-/302019909747
Preferably a NOS one, but I've had experience with several of these Japanese sellers, and what they sell invariably fits the description, plus they're generally always good to deal with, so I wouldn't baulk at importing a used one from someone such as the above, or from the likes of 2juki or foxtan - all ebay 'stalwarts' with vintage gear.
Or, this lovely NOS C1, which whilst not as good as an SA or GL, will certainly outperform any currently produced DL-103, 'R' or otherwise:
