Welcome!
These early 70s kits typically run in the 150-250 range, however it appears there is a Ludwig Supraphonic lurking at the snare station so that could drive the price up a couple of bones, if the seller knows what he has. If they are Presidents, by the lugs they appear to be, they could go as high as 350, if they are fiberglass or wood/fiberglass shells, maybe even a little more, depending on your location. Some areas of the country have much stronger vintage MIJ markets than others, and that tends to drive the selling price more than anything else. In our area for instance, they are hard to find, but sell relatively cheaply, whereas in the Seattle and Portland areas the MIJ enjoy a much stronger following, and hence garner higher selling prices.
BTW, the green bass in front of your kit is a Peal from the late 70s-early 80s, a low end model judging by the lugs and twin tom mount. The blue kit you are looking at is a winner and likely a much better quality buy than the junk pile rescue.
