I see that there is now a ATARI UnoCart 2600 being offered that is slightly cheaper than the Harmony Encore SD cartridge. However according to the specs the Harmony Encore SD cartridge is a better product. The Harmony Encore SD cartridge has a USB port, can switch between PAL and NTSC with a firmware change (the UnoCart 2600 one needs to manually switch the jumper on the PC board for PAL/NTSC games). The Harmony Encore supports cartridge rom images up to 512KB and with a possible future firmware update would allow for games up to 32GB in size by paging in 512KB at a time from the 32GB SDHC card. However its my understanding that the UnoCART 2600 supports cartridges up to 256KB in size.
