Which brand of speedbooster?

I'd like to try a speed booster on my new-to-me NEX 6.

I have a bunch of EOS lenses, so I would need one with contacts to get aperture control

I have a couple of old MF PK mount lenses

I have one MD mount Rokkor

I've also used and loved in the past (but don't have currently) Pentax m42 lenses and Canon FD lenses.

Just looking for recommendations:

1) Which brands of speedboosters do you trust? On eBay, I see a lot of knock-offs. For lenses other than EOS, does anyone have brands they've tried/trusted?

2) Which mounts do you recommend boosters for? At $100+ each, I don't want to collect a bunch. Should I do one for the Rokkor? Should I just bit the bullet and get the more expensive EOS (but EOS lenses MF is terrible). Is M42 more versatile?

Any thoughts/experiences are appreciated.
