Thank you for the link... I will need to review...I don't know why you can't get them in the States but you can order parts from countless shops in Europe and shipping isn't that expensive either.
Here is one example of a shop that stocks all kinds of Apeks parts, kits and tools: regulator revision & workshop
Old dog diving ... ( 1980's ) so that is my bag
Apeks (as a brand) is almost as old as me... so there is interest in ( legacy brands... ) however I shy away from the legacy TAX ( ergo $cuba-pro ) my A700 G50v and mk25 mk 2 r195 will be sold when i get back to japan...
Even though I can get service I am paying a premium with Apeks and getting parts for life I will have a yearly trip which will need to happen for service to keep parts for life or I hit the black market for parts and pay top dollar ERGO ($CUBA-pro tax)..
Now HOG DiveRite DeepSix it is all about service depots and or getting certified to service...
this is where the things meet up as long as I do not need to ship gear somewhere to service ( just like in the states you go to your dive shop and you get your gear serviced... ) with the natural 1 week turnaround .... not 2 week 1+ month turn around.. then that is a solution..
This is the solution I need for Japan and Korea... so I am not servicing three sets+ of gear every April as a birthday gift to myself and then buying another reg set to use while all 3+ sets are being sent out for service... or flying back stateside to visit family and use the excuse to service gear was well.
That is why I am sketch on gear as I have been burnt before not looking to be burned again..
