TDI, IANTD or DSAT
After 20 odd years of diving, I'm getting a bit fed up with 9 min bottom times at 40m where all the interesting stuff lives hereabouts so I'm thinking some deco training won't go amiss.
I've got a dive on in a couple of weeks which will go 39m, I've been diving with twins on & off for a while now and intend to run it as a deco dive using DCIEM tables, on this ere wreck:


I'm looking at doing an Advanced Nitrox & Deco procedures course - if I do this on the mainland, I have the choice of IANTD or TDI; TDI is cheaper and IANTD requires that you do their Deep Course too, whereas TDI accepts logged experience of 10 dives past 30m, which I have in spades.
Courses on the mainland will involve travel by air, which means I'll have to hire tanks etc over there, otherwise, I could take the ferry to Melbourne & drive but this is 4 times the cost of flying. There will also be at least 1 weeks accomodation to pay for too.
The other possibility is to wait until my LDS gets set up to teach the PADI DSAT course which will cost twice as much but has the advantages of nil travel and I stay at home. The DSAT Tech course also includes Extended Range, I believe.
Anyone got any thoughts on the relative merits/demerits of the actual courses, because these will be the deciding factor in the end for me. Or is it a case of the instructor being more important than the course?

I have a few faults but being wrong isn't one of them.
