Thanks very much for your thoughts people - one thing I will say before anything else (and slightly off the subject), is that I apologise for no being able to respond straight away!  Can't seem to get extended periods on the net at the mo, what with work and all, and have been annoyingly busy in the evenings, so please don't think me rude if it looks like I'm ignoring your good advice!!

Back to the matter at hand though - the instructor over here is actually proposing to "package" the basic and advanced NITROX in one go for the princely sum of £180 (don't know how this compares with others).  My friends and I are supplying all equipment, as well as the boat and fuel, so if this appears cheap that may well be why.

Given this option, would that affect your choices?

Also, in response to Steve, I have a Halcyon plate & Pioneer (singles) wing, so would have to upgrade to a 55lb explorer when getting a twinset.
