Mic stand attachment for stereo miking?

Can anyone recommend a good quality mic stand attachment for holding two mics on the same stand? I'm looking for something that's durable, easy to use on a boom and allows me to position one mic higher than the other for XY miking. I've seen a few online but none that make clear whether or not it's possible to adjust the individual heights.

Hoping to spend less than $50 if possible.

Get a nice one and trade me.

I have this and it's not so good b/c the Mics touch each other when they approach the 110 spread. Better than nothing though.

gswitz, I was gonna post the same, I got one for Christmas but it's difficult to use for me. Mics are too heavy, the sides aren't even close to symmetrical and only one side lets me set my own angle. Eh, it was $4.

I use the K&M adjustable bar for cardioid patterns (the sliding one, not the bending arm one).  It has a 3/8" euro thread instead of the 5/8" US standard, so you would have to use the thread adapters that usually come with mic clips.  If you need extra spacing to overlap the mics, you can always use a combination of thread adapters like a 3/8 female to 5/8 male adapter inside a 5/8 female to 3/8 male adapter.  That will give you the appropriate height and only costs a couple bucks.

Is there enough thread to raise a microphone? I'm guessing you'd need about 1.5"-2"?

This Shure stereo mic adapter is pretty interesting, too, but more than your $50. You could probably get it cheaper.

This is kind of fun, like a refresher course for me. I don't have any pairs of mics, yet, but plan to and these kind of bars/adapters are good to know about, even for trying out my mics with the Gold Digger and Cherry Picker.

Raisers only need to be half an inch for the mics to cross at the same angle, the standard diameter of most SDC's.  The capsules should be as close as possible.  

Ah I guess my guesstimate was way off! I'm actually thinking of buying a pair of AT 4041's and I see the diameter is 0.83". 

When it comes to Blumlein bars the heavier the better but you need a strong stand with a good wide spread on the tripod part to allow balancing the weight of the bar and the Mics you use.

Strong stands are an important investment to protect your mics.  I have the On Stage tall stand with heavy Iron base, and it does a good job.  I have abused it to death on the road and it has held up well.  If I need to extend the boom out horizontally with a heavy pair of mics I do use sand bags to reinforce the base.  It is no Latch Lake though.  

Most of the time I will use tall aluminum light stands for ensemble recording.  Since they only weigh a pound or two, I always drape a 35 pound sandbag over the pole at the legs before extending it.  You would need a running tackle to knock the thing over.  I think it is important not to cheap out on stands, if I am going to stick a $4000 pair of mics 13 feet in the air, I want to make darn sure whatever is keeping them up there is equal to the task.
