Two of my three thermostats are Ecobee 3 lite.
I would like to replace the older Honeywell with one.
How hard is the install?
I do have the C wire, as I read that can be an issue.
Do you have to do much/anything inside the furnace?
The HVAC people we use want $385 for the item and the install
The unit itself is about $150ish, so the install is about $235, which seems a little steep.
The instructions online say it should take about 45 minutes for a DIYer.
I also need to check and see if my EMC is offering any rebates.

Jeez, as I recall it was pretty dang easy. I bought an Ecobee 4 around Christmas of 2017. I vaguely remember having to connect a wire at the furnace, but I recall it being very straightforward. And FWIW, Ecobee customer service is very good with walking you through stuff if need be as I recall.
Definitely check your utility company's website for rebate and discounts. I think we paid $49 for ours through an affiliated website. No rebate, just a discount.
This is MA, but just for example:

I replaced a Nest with an Ecobee 3 several years ago. I had no c-wire and the Nest required one to charge or the fan would start and stop in order to charge the Nest. I called Ecobee customer support and they had me send a photo of the Ecobee hook-up and the furnace circuit board. They then walked me through using an spare wire to install the c-wire. It’s been running fine without any problems for the past four years. Great customer support and it only took me about a half-hour to do the install, including setting up the c-wire. Five stars for Ecobee!!!

Nice.
It looked like the website had lots of info and numbers to call for help.
I might give it a go.

Yeah, the best my EMC is offering is $25 off an install. Lol

I felt like the EcoBee installation was super simple. It took more like 15-20 minutes here. We were also moving from a 20 year old Honeywell and had a C wire already.

What level of programmability doe the Ecobee have?
I have Honeywell thermostats, and they have wake, leave, home & sleep.
But I want basically "infinite" control ability, at least more than the four periods the Honeywell gives me.
Just had my solar activated and I want to cool/heat during the day and minimize the need to run my system when the sun is down.

It's pretty programmable. Days of week, times of day, vacation, etc. Plus with the app you can adjust pretty much everything on your phone.

Yes, I love being able to control remotely.
I don’t set specific run times, but I like to be able to adjust the thermostats on the top two floors without having to go up the stairs.
I also like being able to see what I left it on and adjust as needed, remotely.

That sounds very good.
I think I will look very closely at the install guides and see what I think.
The HVAC guy was out here today to do the semi-annual check up. He seemed to imply it was a pretty easy install and that I could probably do it.
I had him look to see if I had the C wire and he said I did.
That seemed to be the only sticking point, if you don’t, there are extra steps.
