So my border collies birthday is coming up in April and we actually share a birthday. I'll be turning 19 the day he turns 1!

So as a birthday present to him and myself, I want to start him in agility. I'm not looking to do it competitively, just something I can set up outside and we can do for fun. Who knows maybe if he does really well I'll look at doing it competitively. I've been looking at some agility kits and they don't seem like they'd hold up very well. This one seems like the best out of the few. Has anyone ever used this?

Would it just be better if I went to Lowes and built one myself? Any recommendations on a book for this kind of project? Like a how-to.
Thanks!
