I have added another page to this blog which lists tadpole trike models by their price. I did this to make a handy tool available to those who have a limited amount of money to spend (or have in mind to spend a certain amount) to buy a tadpole trike.  The page shows the models available within a certain price range and they are listed in $500 increments. HERE is a link to that page.

If you notice any trikes not listed please feel free to bring it to my attention. Thanks.
