I got a new cube when I was averaging over 30.
To be honest, though, with your times, it wouldn't really make a difference yet.
Actually, I think it would make a huge difference initially. But I feel like after the switch, you'd hit a barrier much faster and get discouraged more easily. Using your SB until trying to break sub-30 should be more enjoyable, since the new cube will prove to be useful
Just keep on practicing!!
