I was just wondering where i could get some of these, i've never seen anything like it

Get a set of throw overs, no mounting frames to bother with!.

i just like the look of the solid ones.

Seen some on Flea Bay, but not in recent months!

makes it quite wide. I've seen the frames for sale on ebay. Roundabout £110 ish? None there at the mo, just had a look.
I suppose you just get universal panniers n fix em somehow.

A top box and a holdall with bungee straps will do just as good. 2 black bin liners as waterproofing!

As Liam says, use a holdall and bungy it to the passenger seat.
