Hi zen4life,
OK … this is part 2 of my reply to your last post.
First of all … there are several components to the type of topper you are considering that would affect their performance, price, and “value”. One of these is the type and thickness of the latex itself (3" of Dunlop latex in this case). The second is the amount and type of wool that is used in the quilting. Different manufacturers will use different amounts of wool and different wool suppliers also have different types of wool with different properties. Third is the type and quality of material that is used for the cover (in this case organic cotton). Finally is whether the topper is one sided (the wool is on one side only and the two sides are different) or two sided (the wool quilted cotton cover is on both sides of the topper). Two sided is of course more costly to produce.
Here are a few examples of various different types that are similar that are pre-made with various combinations of these materials (all with 2" - 3" of Dunlop and wool and cotton in the cover) with a focus on “organic” or at least natural and as you can see … these generally are quite expensive (and in some cases more expensive even than the one you are considering). These are in no particular order or chosen with a focus on “value”, just examples of some of the choices that are available.

While this certainly wouldn’t be a complete list … it should give you a good idea of the range available when you go with an “organic” pre-made topper of this type. Using only 2" of Dunlop or removing the wool would add to your options and reduce the price.
Now lets compare this to the alternative which is to buy the materials and components separately.
First is the 3" 100% natural Dunlop latex topper. There is a list of latex topper suppliers … some of which are raw latex without a cover and some which include a cover which are listed in post #4 here and there is also a list of topper covers in the same post some of which are wool quilted as well.
Now all that is needed is to decide on a wool layer to go over this if necessary. There are many options here which vary in price and amount/thickness the style of the topper/pad but a likely “rough” comparison would be in the range of 1 - 1.5" thickness. Of course you can “adjust” this if you choose to.
Some of your better options here include …

Post #3 here also has more sources for woolen mills and wool toppers.
There are several variables between these two approaches and several similarities. If you choose 3" of natural Dunlop latex of the same density … then these will be very similar between different manufacturers. Stretch knit covers will come in different options but these too will be similar in terms of how they affect the topper combination. The wool itself in terms of different properties, amounts and densities of fill, and different quilting or tufting will be the biggest variable. In addition to this … separate components will be slightly softer than everything made together in the same product because they can act more independently. Of course the advantage of the DIY approach is that you can customize the layers of the topper to your preferences and also that you can replace each independently if one “wears out” or needs replacing before the other. The biggest difference is in value where the DIY approach not only can have the same or even better quality materials but can end up with a significantly lower price than most of the “pre-made” options.
There is also a difference between the different choices in terms of return privileges and shipping policies.
Of course you also have the option of using Talalay (has a greater range of firmness choices) instead of Dunlop with either approach.
With this approach … you also have the ability to buy just the topper/cover combination first and see how it works and use your experience to help you choose the type and thickness of the wool topper that would best suit you.
