Looking for a new laser

The two laser machines I currently own are a xTool M1 Ultra (the FULL bundle) and a Creality CP-01 which I mounted a 40w (input) laser onto soon after getting. I find the Creality with my laser setup is great for cutting and fast marking anything but metal. The M1 Ultra has though taken over the job of cutting gaskets as I usually knife cut them now with them at machine. Unfortunately I still don't have a machine that can do metals (the 40w diode can mildly mark alum with brilliance spray, but only very lightly)

I'm wanting to engrave ALL of my tools (STEEL) in my toolbox with my name and a phone number (Makes it hard for someone else to claim the tools) I will be engraving on BOTH sides of all the wrenches so they're always right side up when they wander off so I don't have to rummage. I will also be engraving on sockets, screwdrivers, and more.

I also need the functionality to etch ALUMINUM. I will be using this machine to sell serial tags to work as well as rivet-on barcode and info tags. Currently we're using printed vinyl but the decals peel after a few years, grow algae, or fade. I'd be engraving the Aluminum then coating the parts in Shark-Hide.

I'd really like the functionality of the walk-up engraving on larger panels than I can fit (direct on large items) but don't want to lose the rotary attachment option (I already own the xTool rotary compatible with the F1 Ultra)

Is there a machine that's under $4,000 during Black Friday, etc that fits my needs slightly better than the F1 Ultra? (The biggest being the pass-through option)
