At 18k visits a month, expect the article to be found by search rather than by the site's own readers, which makes the durability of the page the thing to scrutinise.
Where soldmagazine.co.uk is not a topical match for your market, buy it for that plausibility and for whatever brand exposure comes free, and put your exact-match anchors on the sites that genuinely cover your subject. That one discipline is the difference between a general guest post strengthening a profile and the same link making it look synthetic.
Within the General section of the index — 1,576 listings, 39 median DA, 5k median traffic, $70 median price — this placement is 7% above the median on cost and about 3.3× the index median on audience. Listings in that section range from $30 at the cheap end, so the question is not whether $75 is high for a link, but whether it is high for this one.
Generalist inventory also varies more than any other kind, which is why the numbers in this brief matter more than the label. A 38 DA domain with 18k estimated monthly visits and Mixed / stated at order links is a different product from the same DA with a tenth of the traffic, and they are priced too close together in most catalogues.
