I bought the
NovaLynx thermometer shelter and I have been pleased with it. They are currently showing $210.00 (USD) for it. It will be three years old this coming April and it is still in good shape with no peeling or delamination.
I had terrible problems with another shelter from Ben M~~~~. Although it was half the price of the NovaLynx, it literally fell apart in a few months. It was made in China using scrap lumber and some kind of glue that obviously would not hold up to the weather. I'll give B-M credit, since they gave me a full refund for it.
For the NovaLynx shelter, do mount it in an area that is mostly in the shade to the North. Mine has a lot of solar exposure and it ranges several degrees higher than my Davis DFARS stations. I really didn't have much choice for the location, but I wish that I had sited it better. NovaLynx's instructions did state this about the location.
Here is a plot showing my temperature sensor, including the "Garage" temperature which is a Davis temp probe inside of the NovaLynx shelter. The turquoise plot "Gar-shelter" is the probe. It tracks well until the sun shines on it. Again, this is my own fault, not the shelter since I didn't follow the recommendations.

Here is the solar (and UV) plots so you can see the correlation. Depending on whether we get sun today, it may or may not show the difference.
