I havent used brushed for a while and I wouldnt imagine that r/c companies have invested much time in it since brushless became widely used, so I would say LRP Quantum Competion and Nosram Dominator Power would still be pretty good.
I'd imagine you could pick up a previously top end speedo pretty cheap now.
Or you could alternatively go for something new that can do both (but the price does go up)

Depending on how much your willing to pay you could put in an offer for something like this LRP QC3 new on ebay.
