Hi Jonathan, I paid £150 for my silver/gold kentucky chrono in 2005. The strap was broken at the point it joins the case (a common fault I believe). I eventually found a watchmaker that would take on the job to repair it - he did an amazing job - braclet fixed, watch serviced and cleaned - another £150. So £300 in total which is what the generally go for on ebay. One for sale at the moment. Not rare - but as it is aimed at the horse racing and not motorsports it for some reason has limited appeal. I think the kentucky is one of heuer best 70's wathces.
