Tama makes a really nice short boom that is great for guitar.
I'm assuming you mean the MS205ST low-profile stand. I haven't used them, but I've used their standard-height big brother. They're a little light for things like RSM-2 ribbons and other similar giant hunks of iron, but otherwise, they're solid, reliable stands. I wouldn't trust anything lighter duty with actual mics on them. I nearly lost an RSM-2 to a cheap stand once. Caught it with a diving motion just before it hit the ground.
Just be careful to always keep the boom over one of the legs and not halfway between them if you have the boom most of the way out with a heavy mic. Same problem you'd have with any tripod stand, really.
Well, almost any tripod stand. I have a huge tripod stand... probably from On Stage, but I'm not sure since the label is on the part of the center shaft that we cut off to lower it a foot to fit in the piano at short stick. That thing will flat hold anything at maximum extension without falling. Of course, the leg spread is almost as wide as I am tall, so....
I wouldn't recommend the smaller On Stage Stands or Nady stands or Musician's Friend stands or other similar stands (most of the stands you find for $30 and under); they're just too light for larger mics, IMHO.
In this photo, note two things:
1. The silver mic stand that is holding two cymbals and an add-on tom is a Tama.
2. The black vertical post that is sagging under the weight of a pencil condenser is one of the stock Chinese-made stands that gets rebranded under various names like Nady, On Stage, MF, etc.
Hence the reason I recommend the Tama stands.... I relegated the cheap stands to overhead duty because that's all they would hold reliably.
