The reason the B2 is so much cheaper than the B21 is to make it more appealing to the uneducated buyer. With the B2 you are locked into Nimbot only labels that require a thermal ink ribbon. Spending a little more up front and being able to use any label that fits in the machine is worth the extra IMO. You just won’t have multiple ink options and holographic labels as options. Simpler is sometimes better I say , but you make have a creative flare that wants all them bells and whistles.
