Selling kitchen equipment

Hello all, I am looking to sell a large range/oven combo and was wondering what are some good ways of doing so. Craigslist and all that? Or should we go to a professional restaurant supply warehouse rather? It was $10,000 new and is now almost 3 years old, so wanting to get the most out of it obviously. We are located in Durango, CO so not too many large cities extremely close by. Thanks.
