Used dual FW controllers?

My featherweight project is very close to completion, just speed controllers to go. the problem lies with their cost. I don't have much left for fancy ESCs. I've decided to buy a two to three (a spare) dual brushed controllers for simplicity and cost. I'm looking at scorpions, Feather2s and sabretooths (sabreteeth?) mainly, as they seem to have a good track record. I'm open to more brands, these are the only ones that seem to be widely used. If you're interested, please leave me PM. Thank you.

I did send you a PM Theo...
