I'm about to start on a couple of GWR 0-6-0's and I can't get hold of my preferred gearbox, the Roadrunner+, as HLK aren't back in business yet. Looking at alternatives, there's the Comet GB5 which can have a drive extender added that seems to give the same sort of configuration possibilities, and the Branchlines Slimline 2SL box which might also give me what I need. Just wondering if anyone has experience of either of these, before I spend my hard-earned dosh? Many thanks in advance.
