Welcome to the forum...

First question, what type of fish do you want to keep?

I am of the opinion any marine tank will benefit from a skimmer, but you can also choose a wet dry or an under gravel filter with power heads. Julian Sprung has suggested that under gravel filters are still a good choice for fish only systems. I think a combination---starting with a wet dry and then adding a good skimmer about 3 months later will work very well for a large fish only system. I also suggest a thin substrate (less than 1 inch) but that is only my opinion. Personally, I have also had good success with under gravel filters in combination with wet drys---which add a lot of oxygen to the water, but under gravel filters tend to destroy themselves with detritus (even when vacuumed) so after a couple of years the substrate will need to be changed out a little at a time. Also, adding some live rock in the beginning will help create a better environment for your fish in my opinion.

The skimmers I see a lot of good comments on, here and other forums, are the ASM line, Super Skimmer by Coralife, the Won Brothers line and of course the EuroReef brand. Be advised, these things are rarely "set it and forget it" gizmos, they can require cleaning, maintenance, adjusting, etc. Some of the products on the market are worthless junk, choose wisely.

For a large tank like yours I would suggest going with a large sump, housing one of the bigger ASM models like the G3 or the G4 as shown here,:

20% water changes once a week? On a 135 gallon system?! Wow! That's a lot of work! I only do 10% biweekly water changes now and I have a reef tank. If you absolutely need one, you should try a Coralife Superskimmer 220 gallon rating. Not that you need it with that frequent of water changes.

You may be better off with a 30 gallon refugium running macroalgae and small carbon filters tucked away there. If it's FOWLR, your biggest concern (if any, is going to be nitrates). I only recommend that b/c you change the water so often that you may not even need a skimmer.
