Well instead of everything I listed, I ended up getting a Outlaw LFM-1 Plus for 499 w/ free shipping during the last bit of the holiday sale. I cant wait, from what I hear it will compare pretty well to the HSU VTF-2 MK 3 that I was considering used. All in all I am very happy with my choice and think I will get a lot of sub for 500 bones. Some things that swayed me towards the Outlaw was the fact that it was down firing, bottom ported. I will be getting a dog and having a couple kids in the next couple years and like the idea of the sub being "self contained". Meaning dogs cant rip up the cloth grille covers, kids cant stuff sh*t into the ports, etc. Plus the overall look of the Outlaws with the smoked glass tops just appealed to me. Let me know if you guys think I made the right call with a budget limit of 500? Thanks again for all the useful information!
