B2 first experiences

[scubafanatic]

Does anyone know the difference between the B2 and the B1? I found a local dealer who is still selling the B1 at a good price, and I'm thinking about purchasing it.

Also, any info about Atomic reg service/warranty would be much appreciated.

...well, the 'old' B1's had an issue with defective 1st-stage pistons, so you need to confirm 'your' unit is equipped with the 'new' Jet seat piston...otherwise you'll have to pay for the 'upgrade' separately.
