There are several RDAs on FastTech that have multiple versions of the same model.... Some of them will same (Rda name here), (Rda name here B), and some will say (Rda name here "value version)... From what I've been able to decipher (solely based on pics & prices) is there are no real visible differences to differentiate said "value version" from another.. not price, material, color, extras etc.... Anyone with a discernible answer to this?
