Vibration in Steering Wheel & Armrest While Stopped

Could you post a video or audio clip? Knowing the frequency of the vibration will help

Can't...don't own a cell phone, don't Tweet, Don't have a Facebook Account.
Read on another Thread about Exhaust Dampers. Luckily, the 4th mechanic did his research and saw that too! I'm torn between taking it as-is to FL since we're expecting a big snow tomorrow...or taking a chance they'll do that by Friday?!?

Latest: added 4 (four) exhaust vibration dampers to the exhaust system in addition to new engine AND tranny mounts. NO CHANGE! Still a vibration in steering wheel only at specific rpm's (like 700) WHILE PARKED and idling. Me, the Dealer, 3 garages...all give up!
