Lego Investing in 2026

What are people's thoughts on the current state of Lego investing? I'm trying to assess whether LEGO is a market worth committing time and capital to over the next 12 months. I'm considering things like, how long are you typically holding sets for? What is the minimum discount you would usually buy a set at and is it becoming increasingly difficult to find sets at significant discounts? How has ROI changed over the past few years, has it gotten worse, stayed the same...how big of a constraint...
