I just started so I had the set up costs.

Here's what I've spent.

Pilot 1.2 - 1000
Helmet - 120 - light weight - I get hot easily.
Shorts - 102 - They are really really comfortable.
Seat bag - 13
CO2 cannister and refills -25
House pump - 34
Lock - 13
Heavier lock - 17
Tube - 5
Levers for changing tire - 4

$1333.

I haven't gotten a bike computer but would like one.

The last bike I bought was 25 years ago. I rode that thing to death for about 5 years. It didn't owe me a nickel or a dime when I stopped riding. It brought me so many happy days that it was worth every cent I spent on it and more. Lots more.
