I've being getting vibration from motor and underneath the car and wonder if I should get it balance....Anyone has experience with any shop in Portland? results?! Thanks

There are simple things to check.... driveshaft center bearing, universal joints, output shaft bearing and pinion bearing. When I got my current car it had an awful driveline vibration(awful for me is acceptable to some.....) I had nearly a whole car of spare parts at the time so I replace the entire driveshaft, and center bearing... it got better, but not fixed. I checked for play in the differential yoke, it spun smooooothly. I decide to replace the clutch, for it is cheaper then replacing the transmission. I buy an OEM clutch plate and disc, along with oem t/o bearing. Bolt it all up... and Viola... NO vibration!! The clutch I removed was from AP. It may have lost a balance weight... or it may just have been poorly balanced... but the OEM clutch was dead on... and solved my problem

Ditto^^^^ alot of things could be outa whack other than driveshaft

if you are lowered you could also be feeling vibrations from pinion angle.
WHEN does it vibrate?

Engine runs good and all, but haven't check the clutch since it's still good...the vibration happens when gas pedal is release from 1st up to 3rd gear, and the rest is smooth...
