Avoid black, it fades to gray in time, is hard to see dirt when vacuuming, and hard to see depth changes which is a safety hazard. The Pebble will will outlast the plaster by forever. If you aren't ever moving, do it.It'll cost less in the long run. Those prices seem about normal for my area in Central NJ. Get a couple more quotes though so you have something additional to go by.

Hi Markbr, Here are my 2 cents: 1. What Filter would you recommend for this. Go with a Pentair Clean & Clear cartridge filter. Easy to maintain and keeps the water crystal clear. 2. What pump would you recommend Go with a Pentair IntelliFlo VS (variable speed). I would also recommend an EasyTouch 4P or 8P (single body system right)? You will get the best interop between the EasyTouch and IntelliFlo. 3. Which Salt water system If you get an EasyTouch, get one with an IC40 salt cell (good for up to 40,000 gallon pools). This way you can use the EasyTouch to control the salt cell. 4. Which brand Heat pump and what size BTU. Haven't had much experience with Pentair ThermalFlo heat pumps but I hear good things about them. 5. Which cleaning robot, I would prefer one I didn't have to connect to tubing, just something I can throw in without work. I personally use the Pentair Prowler cleaner and like it very much. Easy to use and clean. 6. Which Skimmer to buy Admiral S200 with circular weir is my favorite. 7. Which return jets Not sure. 8. Which lights Do you want color or white?

My brand new liner is called Midnight Blue Glimmerglass. I love it! I don't think it's too dark. This was taken after the sun was half off of it.
