I've auditioned the Ultimate Support keyboard stand (Apex Plus with mic boom) for almost a month now.

I purchased it from Music123 (Dan Seda, x1166) which included a 45 day no risk returnable option.

After having used it with my Yamaha Tyros on a number of gigs now, I've decided it's definitely a KEEPER!

I think the Apex Plus perfectly compliments the Yamaha Tyros as it's new longer 18" tribar arms extend out to fully support the Tryos the complete distance from front to back, as well as left to right, to support most all of the keyboard lengthwise as well. In addition, the stand's center column doesn't obstruct any audio/midi outputs on the back of the Tyros as the keyboard has no outputs in its center area Though I realize this was not the case, the Apex stand appears to have been 'custom designed' specifically for the Tyros as even the back (audience view) of the keyboard (sitting on the stand) allows the Tyros logo to appear completely unobstructed, with 'Yamaha' appearing on the left side of the columm, and 'Tyros' appearing on the right side. The dark brown/black column's anglar design also matches the same style & color theme of the Tyros as well. On stage, the Tyros/Apex combination looks both sleek and professional. The look is a big step up from my Quiklok X style Stand, which to me looks more suitable for an 'ironing board' demonstration at the local County Fair rather than a pro music show. A BIG plus I like about the Apex stand is that its legs keep the foot pedal(s) from getting away from you. When I perform, I prefer sitting/leaning on a raised stool as this allows me to access footpedals more efficiently, as I sometimes need to be holding down one (sustain) while pressing another (fill self or vocal on/off). Even in this elevated sitting position, the Apex column height doesn't obstruct my view of the audience, or them of me (my head). Also ,the mic boom conveniently attaches to the upper part of the column making for a great looking all in one keyboard stand/mic boom package.

Ok, so what are my beefs about the Apex stand? The stand is not as lightweight as I'd prefer. It's nearly 19 lbs, but then again it's no heavier than a similarly rugged double braced X stand with added mic boom, and weighs a little less the Quiklok Monolith stand. I was pleasantly surprised to find that the amount of keyboard bounce (with the 18" tribars) was minimal but I concur with reports from others that the keyboard can become unstable if you lean againest the upper top left or right portion of the keyboard where the tribars are not directly supporting. My only other complaint is that the built in 'flip down' carrying handle is not very comfortable or ergonomically shaped to hold.

In conclusion, I highly recommend the Ultimate Support Apex 'plus' stand with mic boom, and especially if you own the Tyros and require an impressive stage presence as I do. The stand is rugged and should last a lifetime, and setup time is relatively quick (under 20-25 seconds). In my studio, I park my Tyros on a Quiklok Monolith stand as it provides ultimate stability, but for stage performance I'm now taking the Apex stand, and I'm getting lots of compliments not only on my music and showmanship , but on how professional & sleek my Tyros with columm stand look together as well. Our music & showmanship is #1, but how we look as well as our equipment looks on stage, creates an equally important visual impact as well. - Scott
