Check out the Walley sub thread on this web site. The modified version will do a large number of things for entry level. Check out the photos of them and the information about how to modify them.

The Nikko sub is...okay. but for the price, you modify a number of walley subs and they will go deeper and farther. There may be some information about modifying it, but I've not seen it.

Beyond them, there are NO ready to run subs that you can go to a website and purchase and it be shipped right there other than "toys". There ARE some builders that will do that for you, but...they are expensive at best...in the thousands.

For an example, check at the Akula entry level sub build thread on the forum that rhymes with rcsoups... review
