TBI conversion, any downside?

In my dreams, and if I were rich, I would by a 383HT and go crazy with fuel injection...

But in reality, I'm looking for a relatively simple upgrade to my tired 350 in my 72 K20 with an SM465.

Is a TBI swap, either from a donor vehicle, or through affordablefuelinjection.com, or another vendor, or even an Edelbrock or Holley system worth it?

I'm not looking for monster power, but rather a dependable daily driver with better cold starting and throttle response.

Are there any downside to doing a TBI swap vs. keeping it carbureted? The only ones I can think of are the upfront costs, and the added complexity/more to go wrong of the engine. I currently run an Edelbrock Q-Jet with a performer manifold and HEI. It runs ok, but hates cold starting, and it isn't very smooth.

For around $1000 give or take for each option, is it worth it? Looking for any and all advice/experience.
Thank you !
