Whatever you have you probably won't be satisfied, because you requirements and ambitions change. At first I was quite happy with ill fitting rental gear, It was great being able to dive at all even down to just 6 or 7m with a guide. Then I wanted something more comfortable, better fitting and mine so I did not waste part of the dive getting used to the gear or guessing weights. Then I wanted more diving without a guide so I did Ow to dive with friends and go down to 18m Having done that I realised I now wanted to go deeper than 18m to look at wrecks so I took deep diving qualification (40m). I then found my BCD and single tank set up was not a ideal as a compact BP&W with twins. I have not changed to BP&W/twins yet because I now realize I cant stay down long enough on tanks and a CCR would be better. If I ended up with CCR & trimix I would probably get bored on the decompression stops and want a diving bell with canteen and TV.
