Looking for a 6.5" sub. Sundown, CT Sounds or Soundqubed?

I had a Sundown E-8 before is was great. Very loud and very clean for the price. I'm looking to downsize a bit for a new build and I'd like to keep a low budget- around $100 for the sub. My first choice is the Sundown SA-6.5, but I'm also seeing the Soundqubed HDS and CT Sounds Meso for a little bit cheaper. The CT and SQ *look* they can handle more power, but I also know looks can be deceiving. I was just curious if anyone has experience with these brands and would they be worth going with over the tried and true Sundown for a few dollars cheaper. Thanks!
