Need Pin Brush Advice!

[Lindsey, Lee, Whopper and Simba]

Hi everyone, our doodle Whopper recently went through the dreaded 9 1/2 month old shave down due to some pretty extensive matting. She definitely seems to be a lot lighter on her feet these days and a little more jumpy! We have a comb, we have a dematting tool, and have a slicker brush, but our groomer told us the best thing to keep her coat from matting again is a good pin brush. We went to a local pet store and the pin brushes there didn't seem like they'd hold up well...any recommendations? We are trying to find a good brush on the lower end of the budget scale. Below you can see the Whopper before and after shots...I'm still trying to get used to her new look.

I call it a rake. I am not sure what it is called in the store. If from Target they are red like the one shown, if from Walmart they are green, same thing just different makers. I like the one from Target better as the one from Walmart lost it's cushy handle and often slides off. It really is a great tool. It isn't sharp and doesn't cut the hair it just gets right down to the skin which I don't think a pin brush could do.
