Stainless steel buckle from DGX is only $3.25 if plastic one is giving you an issue.

Just a comment on shears -- after reading a lot of posts from folks here, I thought it might be a good idea to have them. I bought some (in fact, I've bought several sets). Even the titanium ones seem to have a steel rivet in the center, which rusts and eventually fails. I gave up and went back to my knife, and a Trilobite cutter. I don't do wreck penetration, nor do I dive where there is a lot of fishing done using steel leaders, so almost anything I'm likely to encounter will fall to one of those.
Dumpster, not quite
If diving a balanced rig you should never be more overweight than the weight of gas in the tank, about 5lbs for an AL80, and up to about 10lbs for a wetsuit. If you can not bring a 15lb diving brick up from the bottom of a pool and keep it at the surface without fins, you have no business getting anywhere near a scuba rig. With fins, and the buoyancy brought back to your rig by the wetsuit re-expanding on ascent, you are only kicking the lost buoyancy up until it comes back. At the surface you should be no more negative than the weight of air in the tank, 5lbs. Easy to stay at the surface sculling, and the odds of having a true TOTAL wing failure is pretty much zero. You can always remove and inflate it with a hole at the bottom, but as soon as you ditch the rig, you are positive again.
Ditching weight at depth is dangerous as hell and should be avoided at all costs. It should only be ditched at the surface, and like I said, if you're diving a balanced rig, you are only as negative as the weight of the tank at the surface. For tropical diving, that's only 5-6lbs.
Weight belt cost, $3.25 for buckle + $4.50 for 6ft of 2" webbing= under $15 shipped to you. Super cheap
DIR divers only wear drysuits when appropriate, which is typically due to weather or need for steel doubles. With wetsuits they have no issue with double AL80's, or wetsuits for warm water diving.
