Hi Debra,
I only recently found out about the Tax Cloud myself. I haven't had the time to investigate it much, but it looks very promising. I too had looked at Avalara quite some time ago, but the cost was ridiculous for a small business. I can only hope that Tax Cloud remains free or low cost otherwise it will be just like Avalara.
Ultimately, it would be nice if my mod became obsolete and everyone could move over to the Tax Cloud method.
My suggestion is to really take a look through their site and maybe set up a test site and try out the mod and see how it works.

If you do, drop us a note and let us know how it goes.

Good Luck,
