As i mentioned at the end of the Panasonic 2010 lineup thread i have just purchased a 42" Panasonic v20 Plasma and am now looking for a good wall mount for it.

I want something that will do a full swivel motion (ie TV right angles to the wall) as the TV is in a large rumpus style bedroom and it needs to be viewable from the bed and the couch. Bed is parallel to the wall it is to be mounted on and the couch is directly opposite.

Ones in the appliance stores are pretty overpriced for the most part, cheapest harvey norman one was $999.

Obviously it also needs to fit the TV which is 20KG with 400mm wide x 300mm high mounting holes which pretty much rules out vesa mounts so a universal one is needed. 1030mm wide also so by my calculations it needs to come 550mm ish off the wall to get the 90deg angle.

Have found a couple that seem to do it, anyone have any experience with either of these

Trademe - $250ish

Jaycar - $179

Both seem to have advantages and disadvantages, trademe one looks very solid with double cantilever arms, jaycar only has single arm, but jaycar one says made for 400 or 600mm stud spacing which more suits my wall which seems to have 600mm ish spacing. trademe backplate is only 560mm long.
