Where are you getting lime for this price???
On point about experience and switching to CCR that I would argue, is that open circuit experience does not count for a lot when moving to CC, EXCEPT that it will improve your confidence in the water, and perhaps you'll have more knowledge (which is power) for possible in-water troubleshooting.
You will need to relearn bouyancy control, you will have new pre dive checks to perform, you will check different thing during the dive, you will breathe differently - these are all fundamental RB and OC skills which IMO, would probably be
more easily learned by someone new, or someone with less OC experience. The caveat to this is that there is a
lot of in depth theoretical understanding about gas physics and physiology that you need to understand to safely troubleshoot which normally only comes with experience....
Completely agree on the point of asking "Why do I want a RB?". I had a number of reasons - lots of extended range and trimix diving will
eventually offer big cost savings, and for the more pedestrian stuff the deco benefits of an optimum infinitely flexible nitrox blend at all times is great. The convenience of a well prepared unit offering a weekend of your average diving without worrying about air fills and lugging twinsets about is also a factor. But I'm also the first to admit that I'm also a bit of a kit junkie, and as such also think it's a great toy/tool (delete as applicable)
