Go find the new prices of each of these items. Here is how I would 'value' that offer. The router is a battleship but it is not variable speed and it is old technology (not that that is a bad thing here). No more than 50% of new. The table is inadequate. It is far better to build one yourself. Part of being a woodworker. No value there. The edge guide is useless, as in almost never used. So value that at 10-15% of new. The template guides can be useful but they are inexpensive enough to wait until you need them, which could be a long time. Again, 1-15% of new. If you have priced the router with the plunge and fixed base, then you will have it at 50% of new. The D-handle base is worth maybe 25%. There is a better do-it-yourself way to go here. Retail this is one very expensive switch. The collets come with the router so additional value here.
As for the condition, I would expect it to be in good shape, as that 690 is one powerhorse, hard to abuse. Now add up your numbers and see how that measures up.
My perspective. I taught routers for years, demonstrated at woodworking shows years ago (about the time the 890 came out), and have written a book on the subject. But you have to decide the validity of the advise you get here.
