I got them here
(that's where CounterPunch got them according to his post in another thread about these, which is where I found out about them).
Also, if you plan to get 2 blasters, be sure to check the box under where it says 'Please Choose:' DW-TP03 Max Power 2x Blasters
as that will save you some money.
Everyone (including me) who I've heard from so far received them super fast (I ordered them and received them in the mail THE NEXT DAY
!) so you shouldn't have to wait long.
The quality is solid and they look awesome in FE Prime's hands.
