Advice on depth training

[triggerjockey]

I just wanted to ask and see if there was any input that could be given on depth training. I love to stretch, but the larger the butt plug I achieve, the longer the usable length is. At present, I am having a hard time getting anything over 7 inches deep.
I don't want to spend too much money on any tools that may not be of any use if it will not help me, so, any advise would be much appreciated.

I used to have problems with depth, but then I got a Dick Rambone (http://www.boyzshop.com/the-dick-rambone-dildo_1667.html). If my ass is in a good mood, I'll have the dildo up to the balls in 10 minutes. It sort of becomes a different type of goal, but maybe that will help you.
