Makerbot can print in Flex filament, as well as a variet of other filaments, without modification. The recommended filaments for Makerbot are PLA and ABS, but any filaments with a low enough melting point that dosen't require enviornmental control can be printed with MakerBot. Flex has a recomended extrusion temperature of 230-240 Celsius, which is under the Replicator 2's recomended max of 250.

Our team is currently using Taulman 618 flexible Nylon filament (250 Celcius) and it prints fine on our MakerBot Replicator 2 even without a heated plate. My recomendation would be to buy a printer from whatever brand you prefer and then experiment with different filaments to see what you can print. There will almost always be filaments you can and cannot print with, but most of the time you can find a filament in your tempreature range that fulfills your required specifications.
