Good deals can certainly be had on Craigslist. I recently bought a set of 4 Volvo factory alloy rims on Craigslist with tires mounted on them for $175. It would normally cost $1000 for the rims alone. However many ads on Craigslist are clearly fishy and it is only prudent to be cautious about dealing with anyone on Craigslist for many reasons, scams and physical safety being only 2 of the reasons. The ads for pets seem to have a higher percentage of ads that don't quite look right. Many of the advertisers clearly lack knowledge of the species that they are selling, leading one to suspect that they picked the animal up for free somewhere and are trying to make a quick buck selling it. Buying an animal from such a person could easily bring you the prospect of disease and large vet bills. In my opinion it is better to be safe than sorry. Some of the people in this thread certainly jumped the gun in forming opinions of this ad but I suspect Mr Chainsaw that you had spent quite a bit of time searching for a windmill to tilt at before finding this thread.
