Hi Sibermike.
Have a look at this company
index they are one of Fabers biggest (non brand) distributors, look under "subaquatica" and then "Bombole Faber".
Our company use them all the time for regulators, cylinders,valves, tank bands everything, very accomplished company.!
They wont sell single items to a private individual at trade price, (regretably, but obviously I guess
), but the shop can certainly approach them for the standard trade / bulk discount, it may be worth a price comparison as the Dollar is quite strong against the Euro now.
I must say we use 18 litre Fabers all the time in our commercial operation and I cant say I find them bouyant either, if anything, you need to be strong enough to handle the weight (20 odd kilos) - not everybodies cup of tea,
- if you need them as recreational tanks, I think the 15 litres are more manageable at around 16 odd kilos, but if your dives are deep and cold..............well, I can understand the reasoning.
Let me know what you think.?
