Diving cheap...????
I honestly think some sports are just not meant to be cheap. Diving, skydiving, skiing, golf, equestrian/horse riding/showjumping, etc, etc just to name a few.
The technology involved, cost of manufacture (Doubt you would trust your life to "el cheapo" dive coms, BCDs or regs, right??

), care, effort and time off required itself is a major obstacle for most "normal" working people.)
How many of us have the luxury of 30 days annual leave or more????
If you do have that amount of leave, you're already at a financial stage in your life where you're not "el cheapo" or at least, don't have to be la..

.
The cheaper dive trips/dive equipment/dive support gets, the more (I fear) will be accidents, incidents and complaints as well.
Have we not heard of:
1. Badly maintained resorts
2. Badly maintained dive boats,tanks, rental equipment, etc.
3. Badly organised trips with hidden cost
Why are all these mainly in Asia??? Not the Bahamas or Cayman Islands? Not in Australia? (Yeah....I miss "el cheapo" diving in Tioman, Perhentian.....but hey...every cloud has a silver lining)
My personnal advise is to save up and go for good equipment and good dive trip with well run establishments.
You can camp on the beach and dive....but do it because you want/like to and not the $$$ saving idea.
You will have a better diving experience. (Trust me....it will be worth it!!!
