I need help advice or opinion

I just bought a CCR and thinking to get a booster the problem is my instructor use Haskel mini sport booster to boost s40 and s80 and it works fine .
other people recommended MPS over Haskell as it works the same but cheaper in cost and service kits , my locations in Thailand so its easy for me to get access to parts of MPS

the MPS C2 looks lovely but heavy 9kg in naked version
Performance: Filling a 3L cylinder from 100b to 220b in 1min30 from a B50 oxygen source at 100b,
TECHNICAL DATA
Pressure ratio: 25/1 Drive air: 9-10 bar Piston stroke: 60 mm Displacement: 20 mm Max boost pressure: 340 bar Min suction pressure: 5 bar
Min pumping speed: 15cycles/minute , Max pumping speed: 140cycles/minute

the MPS C1 looks really small and lovely even lighter 3.3 kg but I think I can boost with it only CCR tanks I don't think I will be able to push it to boost bail out thanks S80 ( correct me if Im wrong
Performance: Filling a 3L cylinder from 100b to 220b in 3min20 from a B50 oxygen source at 100b
TECHNICAL DATA
Pressure ratio: 25/1 Drive air: 9-14 bar Piston stroke: 1 x 40 mm Displacement: 8 mm Max boost pressure: 310 bar , Min suction pressure: 5 bar
Min pumping speed: 15cycles/minute , Max pumping speed: 14 cycles/minute

Haskel Mini Sport Booster : its comes in the mid range weight of 5.5 kg
THE MINI SPORT BOOSTER IS FAST
Take a look at the fill times in the table at right. For example, starting with a supply pressure of just 1000 psi, to fill an AL-19 cylinder to 3000 psi takes just 3 minutes. The Haskel Mini Sport Booster is reliable too, with a one year factory warranty. The Haskel name in boosters has long been recognized for their quality.

currently I want to use it for CCR tanks so basically the small C1 is enough for me
but according to its specs I'm not sure if it can boost bail out mix in S80 and s40
if it does that would be super great if not I will have to move to the c2 or Haskel
please feel free to say your opinion and advice
thanks in advance
cheers
