Looking for rgb case fans that connect magnetically. What are my options?

So far I know Thermaltake makes rgb fans that connect via their Magforce connection which allows you to connect as many as you want. They are the CT120 EX. I know Lian Li makes the Uni fans but they are stupid expensive for a 3 pack. What other options work just like Thermaltake? Or is Thermaltake fans my best bet?
