I've got a Celestron Ultima 80mm 20X-60X spotting scope and a Freeland heavy duty scope stand for sale. Scope easily sees mirage and at 20 to 25X (best power to use at long range, any more will have too much image wiggle and will be hard to see small changes in the mirage indicating a change in crosswind speed), can pick out 30 caliber bullet holes in the black at 1000 yards on a cool day when there's no mirage.
Let me know if you're interested.
