I plan to lurk like a trap door spider and snatch one from the near mythical classifieds when baby, marriage, house etc. forces a sale.
Works every time in the rest of the world.
I'm in no rush and I've run custom vs. off the shelf gear before and am aware of the "hole you pour money into" potential for leaving the beaten tracks. Maybe it won't be a MP5 (lesser of 2 evils in my book anyway) maybe a well tweaked AR platform.
Some folks call this living better with information gained while being stupid (or aging for short).
