Tasso and Andouille in Tampa
Andouille shouldn't be too hard, try Whole Foods, or one of our local meat mongers could probably get it for you pretty easily (try Robert's on westshore or Castellano & Pizzo also in South Tampa), and Tasso I'm not to sure, but I know that Paul, owner of Cajun Cafe on the Bayou could point you in the right direction (and he's an awesome guy to boot).
As noted above, you can get tasso at Land and Sea Market along with Andouille. Tasso seems to go a long way, so I buy a block, cut it into pieces and freeze it.
You can get a really good Andouille at Publix, made by Aidell's. Check it out. Also, you didn't ask, but a local Tampa company called Uncle John's Pride makes some fantastic smoked sausage (probably the best I have found) and they also sell ham hocks. I use their sausage in my Jambalaya and the ham hocks in red beans.
Last, I recently came across a fantastic andouille by Leidy's. Not sure where they sell it locally but I buy it at Restaurant Depot. It's one of my new favorites.

There is a group in wesley chapel/new tampa that i buy from at the local farmers markets. Their name is sausage laboratory. They smoke their own andouille over pecan and it was wonderful in a pot of red beans. I spoke to them about tasso and they said they do it but not on a regular basis.
Go to their website to see where they are around tampa. def worth it. B.
