I've used this tool but not yet purchased any of the favorites I saved. I knew a few domains I wanted to buy so went to LDS and opened up the link to the registrar from there so hopefully credit was given (can't freeload).

Only thing I'd change so far is maybe moving the search bar slightly higher on front page, make it and the button bigger and putting light grey text in the search box. But, you've probably thought of all of that already, just my personal style. Anyways, this has been my go to tool for searching for domains since I found it here a month or so ago. Thanks for building!
