$40 is a common price, though HMS in general vary greatly, range on them is usually $30-$80, though the higher end is only NIB, and you can get lower if you're lucky.
It's good for being one of the most useful HMS out of the box. If you're in an area with people who use attackers, it's probably a safer bet than WBMS, though it's still not a safe bet by any means.
It's a good Upper Attack combo out of the box, though I find Jiraiya MS's AR works better on it, as an attacking compact (Kei told me to try the combo, and I liked it a lot).
The AR, Circle Upper, is great for upper attack (w/ upward smash), and can be used for wobbling zombies due to its weight distribution (the lighter first mold is better for this). For attack it is outperformed by Samurai Upper (same metal frame, more aggressive and heavier ABS caul).
The WD is Circle Heavy, which is good for compacts (though the 17/18g CWD metal part and suitable CWD are better, and compacts aren't a big thing in HMS because the system is quite uniform size/weight wise, so there's no major RPM advantage to be gained) and considered good for upper attack (I prefer draciel MS's heavy circle wide for attack, given a grip core, as it emphasises the Upward Smash of all the main Attack AR's aside from Jiraiya Blade, and has better speed and LAD than other WD's)
The Running Core is Metal Change Core, which, if you're familiar with plastics, a great shape for Attack/Stamina balance types (and the shape is quite underrated for defensive use). It's no Grip core, but it's one of, if not the best, incarnation of the Metal Change tip, being very controllable for both Aggression and Survival.
But yeah, main thing is how good it is out of the box (with more versatility than WBMS) and how good its parts are in general. WBMS is a better choice for attack-less areas, and probably those using Tornado Balance as a stadium.
