Need a pair, matching tanks for doubles.

While I'm here...
I have a LP45 Faber/Scubapro, current hydro, current vip, o2 cleaned and filled with o2
I could be wrong about the LP45, could not find the marking for the capacity, and it's rated 3000 PSI, the tank size is consistent with a LP45 though.

Also have 2 Genesis HP80

All DIN.
Thanx!
