What is your cut-off point money wise in deck building?

How much is the absolute top dollar amount you are willing to spend on a deck?

I have four decks in my top decked app that I use to build decks then buy them and I average $350 a deck with the lower end being $228 for my Simic Merfolk deck. I know money doesn’t mean anything if you can’t pilot a deck properly whether it’s a $50 deck or a $1k+ deck. Case in point, my good friend who introduced and taught me how to play magic has an enchantment deck that he built out of a precon five years ago with $25 in upgrades and that deck is an absolute nightmare to play against.
