Which Piece? Or Suggestions?

Hey guys, got a small aging bong stm 17cm tall haha, good fun but want something a little bigger and better.

I would 'like' the bong to have; (want not need)
- a slider cone piece (no carb)
- maybe an ashcather/perc
- beaker/round style base not a complete tube


So far I have been looking at these 2 pieces;

Any suggestions? money isnt too much of a problem, but I do live in Australia so most of the American blown pieces are out of the equation.
