If you can move your budget up a bit more to say $500 you can start looking at the Internet Direct sub manufacturers such as HSU, SVS and the like. That being said I went from a crappy HTiB sub to the PSW110 and was pretty happy until I realized what I could get for the same $250 although I didn't pay $250 at the time lol. It produced a lot of mid bass but that was basically it. I then moved up to the S10.3 and it was much better. Way more output below 35hz where the 110 would roll off steeply, down to the mid 20's, clean and more output above 35hz as well.
After getting some advice elsewhere, I actually had the same thought and moved up to the pl200 last night. 80 more but seems like everywhere I read said it was a solid improvement.
