Ditto. The good ones are very good- I now have an obscene number of them (actually, 8 bodies as of today, and 20 capsules). I've used them for drum overheads, XY and ORTF coincident pair recording of small vocal ensembles, live recording of large choral ensembles (~150 voices), acoustic guitar, and even got good results on a baby grand piano with a pair of them. I use them for live reinforcement/recording of a capella vocal quartets, and have no heartburn at all taking them out for live dates where there's a finite chance that someone will either swipe them or roll the piano over them.
For the large chorus, I've used 6 at a time rigged on battens and flown in overhead. For a Christmas show this year, I did that with the hypercardioid capsules so that I could pick up the vocal work *behind* a 7-piece Dixieland jazz band that was set up in the center of the stage, inside the arc of the risers. The omni capsules are very flat, and all in all, I *like* this mic (with the set of 3 capsules) as the bang-for-the-buck leader, when versatility is considered. The good ones are very good.
The bad ones, on the other hand, *suck*, and problems may not reveal themselves instantly. Use your ears carefully before you buy. I've had two bad preamp bodies, and two bad capsules (one omni, one hyper)- all from Guitar Center. Serves me right- I didn't listen long enough (to catch the bodies, which go noisy after a while if they have a failure coming on or are badly defluxed), or to all the capsules in a kit (because I didn't think I'd ever need 6 hypercardioids: *never* say never....).
IMNSHO, it is worth paying the extra money to buy them from a vendor that will sort out the culls and DOAs for you. The first ones, I bought from GC, because I needed them *right away* (for a gig that evening) and they were there. The later ones, I've bought from The Sound Room. Taylor has also fixed my two noisy GC bodies, and they are just fine now...
If you choose to buy from GC, listen _with headphones_ for at least 15-20 minutes per body. Use heat (and moisture) from the palm of your hand to warm up the body, and listen for LF rumbles or basso pops (rumbles or thumps that are indicative of flux/PC board cleaning problems). And listen to each and every capsule if you get the kit of 3. QC is very spotty at the Oktava factory, in my personal experience.
I like 'em _a lot_, but your mileage may vary.
I'm jonesing very heavily for a pair of the Lomo M3 capsules also. To probe further, or to find out about The Sound Room, go here:

I also have some Byetone dynamics from there that could actually be used to drive nails, and sound good for tuba and way-over-the-top mic-ape vocalists...
