No big diffrence really other than brand name, and I think you get a few more degress of up and down travel in the Place unit over the berk piece.
Another thing to consider is that ALL the parts for a Place unit are readily and cheaply available where as the berk probably not so much on either account.
6K is a little on the high side for a splash of a boat you can get for about the same price.
Either way those Southwind/eliminator splashes are popular and so long as it checks out structually I'd be able to sleep at night.
