Have to agree with the others, please do try classes, you need to learn the basics under tuition first or you and your dog can learn an awful lot of bad habits which you would then need classes to fix but would take a lot longer.
A full kit second hand like ex-competition kit can be around £1800+, that`s a lot of money to spend just to get things wrong - and to risk potentially serious injuries - through not being taught properly for a few quid a week instead, and is a lot to spend just to find agility might not be her thing as it were
There is also a huge temptation to train far too much with home equipment, once a week at a good club is enough while learning the basics and enough to later become competent to train at home by which time handlers have learned how much or how little to do more frequently but in shorter bursts than at a standard weekly class.

**I know Angel is old enough, but for general info for others considering agility at home or otherwise, all dogs should be 12 months minimum to start full agility training, older if a large breed.
