These are great recommendations. They also require changing what you do, which can be difficult (at least for me).
I try to use a simple framework (not mine):
Is this decision easily reversible?
- If yes, make it quickly and imperfectly.
- If no, take your time and invest in research and options.
And BTW, even in this market, most bicycle purchases are reversible 
. You might spend $100-$200, but that’s about 4% of a $5000 purchase - less than sales tax in many places.
