axesrus (in my home town none the less) were the first place i found them but i got them on ebay for half the price.
they are a good set and they hold just fine with the tremolo, the low E can go a bit flat but that always happens with tuners.
I did have a weird problem with them the other day, i tightened the screws that hold the heads on and one of the screws just popped out and wouldn't go back in, seemed like it was too short to reach the threads inside so i took a screw out of an old set of tuners that were longer and put that in instead, worked fine.
I think the gear ratio is as standard for 10mm bolt ons, if there is such a thing, not too high is all I can say.
