What are your favorite Blender Add-ons?

[Gordon Nadezda]

I've been considering purchasing a few Blender add-ons from Blender Market, but there are so many to choose from. So, I wondered. What are some useful Blender add-ons that would help with the creation of SL assets? I should mention that my primary focus is static objects/mesh. 

I was particularly interested in a couple of add-ons. One is called Bake Helper from MeshLogic. The other is BakeTool. But, I'm also interested in feedback on other useful add-ons. 

I hope this is the appropriate forum for this post. If not, please let me know.

I've only used free ones , the most useful of which is related to 3D printing .. not really felt the need for anything relating to static models for SL.
