Long time Ozbargainer! Been more of a stalker than a poster tbh. Thought I'd contribute, as I have recently thrown up a website for my business. Just starting out with the website, so I only have a couple of products up, but these are one of my most popular printers, so I thought I'd start here.
Brother MFC L3770cdw - $495 - Link - https://allpnc.com.au/product/brother-mfc-l3770cdw
Brother MFC L8690cdw - $680 - Link - https://allpnc.com.au/product/brother-mfc-l8690cdw
PLEASE - Check the postage and handling on competitor websites, before saying "this is cheaper here".. If you find it cheaper, please let me know, but I believe this is a very good price for these two machines. I'd recommend going through the whole process of getting yourself to the checkout to completely verify it is actually cheaper.
For those who require the service - I have an installation charge as well, which includes me collecting it from my supplier, delivering it, setting it up, installing on your computer, removing the packaging and also disposing of your a4 printer as an option.
Regarding our Premium Compatible Toners - I have ordered from MANY suppliers, and after losing several clients to poor quality compatible toners, I have been able to filter out the bad from the good. Of course, I pay a premium for this quality, which keeps me from replacing warranty toners often, and keeps my clients satisfied with print quality, and pages they receive within that toner cartridge. I also have the "economy toners", for those who don't mind print quality issues, and are just using it for in-house/draft style printing.. you do get what you pay for, so please keep that in mind.
I am very transparent in my communication, so please reach out if you require anything else. Also happy to add more products onto the website to suit the OzBargain community, so please request any printer related products you may have in the comments and I'll see if I can help you out :)
Good price indeed.
And best of luck to OP for your business.
