We bought a really decent color laser recently which we got cheap 2nd hand (about £50) only had two faults which was a dent in the transfer belt and a chunk taken out of the upper fuser roller.
Got a box of fusers (5 used for £40) with a view of making one good one but it seems they all work perfectly so that was a 5 minute replacement.
Also spotted a new original transfer belt for £70 posted so that was a 10min job. Though afterwards it was ghosting but a quick menu change where I upped the transfer voltage solved that issue.
Consumables were all 90% and not clones so fine for a few thousand pages.
So for £150 and a bit of work I've got a £500+ printer that is doing great for number plates, vinyl stickers and 37 pages per minute printing.
not fixed a laser since I worked in an IT workshop back in the late 90's, glad to see I haven't lost it
