F5 Rack Rental

Hello, 

I'm new to F5 and did my 101 last month. 

Sorry to ask this question. Does anyone know where to find some rack rentals so I can practice for my 201 exams? 

This question could be playing an old record over and over again in this forum. Unfortunately, I couldn't find any solid answer.

What paths you did take to build up your own lab? I heard F5 rents $95 racks, couldn't find any details on that either.

Thanks in advance.
