Opinions on attached prim number

Hey all, starting to build a series of avies.

I hear a lot about attachments causing lag. I would love to hear some experienced techie/builder opinions on what you would consider an acceptable number of prim attachments.

I'm specifically looking for a happy medium of as much detail as possible without negatively impacting the owners' or people surrounding the owners SL experience.

I thank all of the SL geniuses in advance for your replies

lol if you dont have the pimped out avy someone else will. ill leave it as that. no one is really considerate about others anymore it seems.

Well, let's assume that I would like to attempt to be considerate

I also believe that marketing an avie as low-prim could make good business sense (depending on what the community thinks the happy medium between low-prim and avie quality is).

Any other thoughts?

speaking from a non tech point of view.. use common sense you know what tacky is? well to much is tacky.

Not talking tacky here.. I've got a pretty hot design sense

Putting aside the asthetics of the avie itself, I would like to hear more about usability.

Thanks
