@Likun yeah I agree with FlyingLow, those are pretty similar to what you already have (I also think matrix are not good perc for vaping really, I have that modular piece, with just the circ perc and main can) and it depends what you are looking for exactly...
I think inline perc, with right angle style female joint, would be nice for you to get instead of the downward perc (dewar?) style again, like if you don't mind not buying from China, the GooRoo large inline would be perfect with tetra and enano... It has a great unique inline perc, full of holes, and it is also larger than anything I've seen on DHgate (most of their inline bubblers are much smaller and just simple slits in the perc) so great compliment to what you have already!
This looks like a good option if you want to try a double perc, inline to mushroom circ perc...
This one has a unique perc and is well-reviewed, tall tube with the fab egg for extra cooling...Or go for the tall straight fab, mine is great with my tetra and would be good with a log, there was a nice green one shared in here from a different website with slitted fountain perc... Also
this one always looks quite good to me, also the inline perc below honeycomb to fab egg larger ones I've seen look like they would function fantastic.
If you want more of a recycler,
this style of fountain perc below klein funnel is popular, there are many different types and sizes for it, though I actually
really like
mine that has a different design with an upline tube instead of a downline tube, and incycler downline tube instead of incycler upline... Creates the perfect recycling vortex cyclone in use, fantastic balance of diffusion and flavor!
Meanwhile
this 9.8inch circ perc rig actually looks quite nice! Basic function, but solid, and some pretty etched glass, the blue glass is even a little transparent it seems:
