Found a steal on a 340c from a member over at AVS looking to unload it.
After much deliberation and the sage advice of those who have tread before me (found here):

I've decided to forego my original plan of 170s all around and pulled the trigger on the 340 center. Someday in the distant future (after the sub upgrade) I'll pick up anothe pair of 340s and move the 170s to surround duty.
Ultimately I decided the 340 for its slighly lower extension, slightly better listening window, and for the upgrade path to 340s in the L/R slots. The voicing of this speaker appears to be very close to the 170s based on FR plots so I don't feel I've strayed too far from my original intent.
So my logitechs have been hanging on nails in the wall - somehow at 14lb a speaker I don't think those little nails arre gonna cut it. Sometime in the next few days I'll build some temp stands out of some spare MDF I have in the garage.

Oh, by the way, my impressions from Star Wars EP III- great special effects... wasted on a smoldering pile of crap of a story. I laughed out loud at the end when the newly costumed Dark Vader finds out about Padme's demise and, shaking his fists in the air, yells "NOOOOoooooooo!" Somehow it struck me as something out of Spaceballs, not Star Wars. Oh well.
