depends on the price. Read through the threads in here.
You can get a new top of the line BP/W for $500 from Deep Sea Supply. Can go down to about $400 or less if you shop around and make some compromises
Hog regulator set brand new for $500 with SPG, matching second stages, etc from Dive Right in Scuba. Used regulators are much cheaper
Computer $170 for Zeagle N2ition from Dive Gear Express
These will literally last you until the end of your diving career and that is without trying to shop for price. BC's don't need service, Hog regulators can be done yourself if you're mechanically inclined. I would not buy anything in that set except the first and second stage *wouldn't pay more than $200 for that*, and the AL80's, which depending on age should be absolutely no more than $75 each. If the total package is at or under $400, it might be worth it, and then sell the BC with console/air2 and keep the rest for $200 and you did pretty well.
Buy your last gear first. Local service is a joke, most of the "authorized repair technicians" are complete junk, not saying yours is, but don't be swooned by them unless they are truly reputable. Don't buy a brand based on the prospect of local service, it's a horrible decision, buy based on price vs. performance, and what you need long term.
If sidemount looks appealing to you, don't buy backmount gear. If any sort of technical diving/training looks appealing to you, buy a backplate/wing and proper regulator set, you won't be allowed to do technical training in that bc with an Air2, so why buy it now? No gear in any sort of technical diving is limited to those divers. Poseidon is teaching divers how to dive in the Poseidon MK7 CCR, their open water was done on a rebreather. People are learning how to dive in sidemount from day 1. We teach everyone in a BP/W from the start. Look at your long term diving goals, and buy based on that so you only have to buy once, you may choose to buy again, but if any of the above sound appealing to you, the only thing in what you listed that will transfer are the tanks for stage/deco bottles, and the first/second stage which will have to have another second stage added, and a plain SPG attached, which will cost about $200 minimum.
