I got my Rigol DS1054Z today, and already used the online keygen, for the additional bandwidth, seems like a really nice little scope, with 4 channels. And so much faster to set up than the PC based scope I'm used to at work(automotive).
I also got a free Uni-T DMM with the Rigol, a small handy model, perfect for car fuse checking and such things.
And ordered some bnc to banana adapters, so I can use the original break out cables with my scope, and a hand full of BNC end plugs, to protect the unused ports from dirt.
