I should mention if you just want a basic node, then a Pi will work, but if you want lighting channels and extra features, it's prob best to upgrade.

I wholly agree. I've upgraded to a Dell Optiplex 7040 Micro (refurbished) for cheap and it's a great unit for a node. ~$200 and you've got a i5 processor, 16GB of RAM and SSD with the ability to add another m.2 drive. Lots of these for sale online.
