I am finding that keyword click rates are just too high for our product. The possibility of paying only when you make a sale is great!

No worries. The commission you will have to pay to Google per sale will effectively eat all your margin.
There will always be a suicide burning money no matter what because they are starting or because this is their last chance. These guys will force you to compete against them unless you wish to be on page 1500 of these ads.

My personal opinion is that this is HIGH TIME to work on your brand. This is the only way to go if you want to have any online traffic from Google.

Actually, Bing started doing what Google announced here already - they have the Bing Travel and Bing Travel is what Google Products Ads will be. Go figure and apply the model to your niche.
