Hi mouth047, I bought my Aqualung Legend regulator set at Al Boom Diving 6 months ago. At the time, they had a good range of Apeks and Aqualung regs in stock, so you should find a reasonable selection available (if you are still looking). They also offered a very good discount on the initial and follow-up purchases I have made there, making their prices almost as competitive as buying from an online retailer like LeisurePro or DiveInn Scube Store.
The only issue I found was that after they put it all together for me (reg, octopus, SPG), it started to leak air from one of the high pressure ports on the first stage within the first 2-3 dives As a result, one of the dive instructors on my then dive boat tightened it up and the problem seemed to go away. However, I immediately checked it out with an Aqualung authorised technician and found a damaged o-ring that was on the verge of splitting. I can only deduce that EITHER Al Boom may have possibly over-tightened the hose seal and damaged the o-ring OR they under-tightened it, and the dive instructor inadvertently damaged the o-ring himself.
Lesson learned: double and triple check brand new equipment before diving, especially where crucial seals are concerned!
