I started with the i300 as part of an Aqualung package deal. 15 dives later I upgraded to the Perdix air integrated. It was expensive but not as expensive as wasting money on a budget computer that I was never happy with and only used for 15 dives.
I also upgraded my Aqualung Zuma to a BP/W. The Zuma was a back inflate that lacked proper d-rings and a crotch strap for keeping it from riding up. The other reasons for upgrading from the Zuma are minor but there are several of them. It hangs in my closet and I would dive it if I had to but I suspect it will live there unused unless a friend wants to try it out. So that is another piece of gear that ends up being expensive based on cost per use because I bought a package to save money.
The regs that came with it have been upgraded as well but there was nothing really wrong with them besides the difficulty in getting service parts and the cost and trust factor associated with getting them serviced at the LDS. I have used them as spares and they saved me earlier this month on a LOB trip. I will also use them a sidemount rig as I have found parts.
This becomes a very personal question and answer exercise. I have not made recommendations but rather shared my experience. Advice on dive gear invites argumentative people to argue so try to take argumentative posts with a grain of salt. They distract from the good info that is available here.
