Does anyone etch anymore?

Thank you for the clarification.
500w might do it though !

Hello everyone – 1st time post
I still old school etch, I like to keep my pcb looking a bit vintage
1/ Design in DIYLC.
2/ Capture trace only with snipping tool
3/ Print onto proper wax transfer paper using laser printer
4/ Cut out and apply to cleaned one sided PCB board
5/ Fix with a hot iron
6/ Peel off – touch up any pinholes with a black sharpie
7/ Etch in Aluminium Sulphate – takes around 4 hrs but no sink residue problems
8/ Drill holes with small cheap ebay hand drill
9/ Remove ink with acetone
10/ Re-polish copper with 600grit, clean again with acetone.
11/ Apply tin coating with Tin/Urea salts.
12/ done

Hi.
I suffered from "Brother laser ink and magazine paper may not work".
Switching to toner transfer paper fixed things.  The "put your name on a coffee cup" type.  Print, slide the decal on, dry in oven, peel off plastic backing, bake toner on.
I've found:
Don't dry the decal too much.  You might not get the backing film off.  3 minutes at 70 C (recommended for my paper is 10 minutes at 110 C).
No need to do the final bake at 180 C for 10 minutes. 150 C at 5 minutes is plenty.
Tracks need to be at least 0.02 inch wide (about 0.5 mm).
Ammonium persulphate 1:8 at 70 C etches in about 5 minutes if kept hot.
5g of persulphate is ample for 50mm x 25mm of board (2" x 1").

I'm way too impatient and make way too many design errors  to send pcbs off for manufacturing.
