| I think the SCR systems are vastly underated. They are the perfect system for most diving to 40m. After this the CCRs come into their own for simplicity of diving. However, the SCR can be used in the 40+ range on trimix to great depths with sensible gas switching. Yes, it is more complicated. However, if you can manage this you will be a better diver. CCR Trimix is for muppets by comparison.
Think about the diving you do and are likely to do and pick a unit to suit. Do not go for a CCR and then feel obliged to find dives that you think will justify your expenditure.
Dive for enjoyment!
