With my tools I used "bleed" Delta gray paint but after this last corporate screw up, it would be hard for me to buy a Delta product.
Depending on your future goals in callmaking determines your future needs. 4" quill throw is nice, longer is better. I have a 3 and 1/4 quill throw on one drill press in New Mexico, if I need more I can drill on the lathe. Most of my designs don't require the longer quill throw, so I bought a Rikon bench model brand new for this shop.
There is a plenty of money that can be spent in this hobby, if you are frugal you buy what you need, not always what you want. If funds are unlimited, go for what you want.
