I have the MC Makpo Rubinar 1000/10. Well, that's how it started out. (It cost me US$225 on the bay, shipping included.) It is BIG, weighs 1769g naked... and it won't mount directly on my K20D, because of the flash nub. I added about 20mm of macro extension tubes to get it to fit, so now it's more like 1200/12. I could mount it without the extension on my ZX-M but haven't tried shooting that yet.
It's not easy to use, even on a sturdy portable tripod. I weigh-down the 'pod to stabilize it, then pile a couple sand-filled beanbags atop the Rubinar to stabilize *IT*. Or I handhold it with SR on bright days, ha ha. The optics are fine, just what you'd expect from a big mirror. I haven't had much application for it yet, not in my dense dark forest; it's going on my upcoming long road trip, so I'll see what it can do.
