Magnum Dynalab MD-100 vs. the MD-102 Tuners

I have been looking for a McIntosh MR78 FM Tuner for months but have found nothing yet. Several were rejected because of poor condition or high price (I need to see the unit before I will purchase). Several friends have suggested the Magnum Dynalab MD-100 tuner and others have recommended the more expensive Magnum Dynalab MD-102 tuner. The MD-102 is $900 more than the MD-100 so this is a budget problem. Assuming I give up on the McIntosh MR78 search, do you have any comments on the Magnum Dynalab MD-100 vs. the MD-102 tuner? Thanks
