I voted Halcyon out of your choices.
I dive a different brand myself, but there are many out there to choose from.
You'll have to research the different BP/W setups if you and your wife decide to go that route.
FWIW...It'll cost you much more than $50 to have a machine shop or sheet metal shop fabricate you a back plate. There's more to making one than most people realize.
1/8" plate (stainless or aluminum) isn't cheap to begin with.
