I am looking for some "budget friendly" options for trailers for jigs and chatter baits. What do you suggest?

I like the Zoom ultra vibe speed craw and the twin tail grub.

Big Bite Baits Craw or any of their similar products. The craw is like $2 for a 5 pack.

For the jigs give the Zman Turbo Crawz a try. It has nice action and is made from elaztech so if you glue it to the jig you probably going to lose the jig before the craw gets worn out. Can´t beat that for cost efficiency...

Berkley pit boss

Big bite baits craw

Yum makes tons of plastics, lower priced and seem to last quite well. 

Missile D-Bombs hard to beat at $3.99 a pack. My go to though is BioSpawn Vile Craw.

Zoom chunk, any grub or zoom fluke for chatterbait, or as stated above, yum products, or pit boss.  All standard and relatively cheap.

YUM has several good ones. The Craw Papi and Christie Craw are two of my favorite jig trailers. Check out the Pulse swimbait, swimming Dinger, or Boogee tail for your chatterbait.
