What would you recommend as a good cheap ,easy to use Chronograph for every thing from bows to CF rifles?

There seems to be many choices available all of which I have zero experience with accept for one. Thirty + years ago my then new bride bought me an Ohler model 35 P chronograph and it is the only one I have ever used and still gets used regularly .
It was quite expensive at $300.00 but in retrospect at $10.00 per year and counting sounds not so bad.
The model 35 P is like having two chronographs in one. It uses three sky screens and gives two readings per shot. The P in the name stands for proof of the fact that you are getting confirmation from one on the data from the other. If there is a discrepancy between the data then you immediately know that something went wrong so dont trust the data from either and re-shoot until data corresponds.
The things that usually go wrong are related to poor fading light or low battery. I have at times been able to overcome the low light problem by setting a flash light on top of each sky screen pointing downward shining light through the defuser toward the photo electric eye. In the sunless Alaskan interior winters this was the only way to get the system to work.
As for low batteries there is only one way to fix that but it is a simple switch of a single 9-V battery. Would I recommend this chronograph ? I think with 30+ and counting years of service it recommends itself.

i got the caldwell kit(2nd one) about 4 or so years ago. my first one(caldwell) killed itself by jumping into a bullet i shot. i don't use it much but its nice to know the velocity.

A key to long range accuracy is consistent velocity with ES not more than in the teens and single digits preferred. Without knowing those velocities you have lost the key to long range accuracy.
Some loads with up to 150 fps ES can shoot extremely well at 100 yards but at 1000 or 1200 or some other longer range can cause extreme vertical dispersion of up to about 10 or so feet.
A chronograph is the only way to know when a load is refined to it lowest possible ES.

Greetings
We bought an $88 Crony 15 years ago and it was working fine 2 years ago when we packed it to return down here.

I have two. The one I use the most is a Shooting Chrony F-1. Very easy set up to use. Great battery life. The whole think folds up into a paxkage small enough to fit into a 30 cal ammo can.
The other one I have is also a shooting chrony, master series with all the printouts and extra stuff. I’ve never used it.
I think the F-1 model Can be had for right around 100 bucks. I use it just about every time I shoot.
