I presume they are Stratus Minis--but there have been a couple of iterations. How old are they. You might also look at the picture in the Stereophile review to see if it looks like the New Stratus Minis (circa 1996 and later).

We have a pair of the new Stratus Minis and we use them in the family room for HT. They are quite a worthy speaker and even can work reasonably well in my main system. They have excellent bass for a mini-monitor and also work well in the near field.
Considering that there are now speakers in the Image series (such as the Image B25) which are more recently designed, I suggest you try some hard bargaining, and try to get them for less.
