Like Frank said,
The Stalker is more comparable to the FX. The Stalkers are 33 1/8" axle to axle, 27" -32" draw length, 40#-70# draw weights, 8 1/8" brace height, 2.9 pounds, and a IBO speed of 306 f.p.s.
I was looking at the Stalkers last year, but, I didn' t have the money back then. They are selling around 379.99-399.99 around here.
What can I say about this bow? It is a amazing package for the tree-stand hunter. The bow is short at 33 1/8" but, it isn' t to the point where you loose accuracy. The bow is INCREDIBLY light. You could outfit this bow with all your accessories and be around the same weight as some bows without anything. The brace height is big which will help with any problems in form and will help prevent the string from hitting your hunting clothes. The speed, though not as fast as most of the other BowTechs is stil VERY impressive.
The bow is quiet, and shockfree. The draw cycles of BowTechs get bad wraps from alot of guys, but, in my honest opinion, they aren' t as noticeable as most people would have you believe (and this is comming from someone who shot just about every bow in Pennsylvania before decideing on my MightyMite this year

) I know the draw cycle of my Hoyt MT Sport with Versa-Cam from last year is pretty much the exact same feel as the MightyMite. The only bows that I noticed have a much smoother draw cycle are the new Hoyts with cam and a half.
The only downside to the Stalker is the grip, in my opinion. The grip is a chunk of rubber (which some guys like for hunting), but, I prefer a very thin wood grip. If the grip is something that bothers you, you could have it replaced with a wood grip, and then there really wouldn' t be any downsides to this bow.
Now, another thing about this bow is that if you have been shooting bows in the 35-37" a.t.a. length that weight in the normal 3.75 pound range, it is gonna take a little while to get use to. The Stalker feels like a kids bow, but, once you shoot it, you will see that this is FAR from one.
If you are looking at other sweet shooters in that price range, check out the Browning Tornado, Hoyt MT Sport, Hoyt MagnaTec, PSE FireStrom. These are all good bows that I really like.
The MT Sport costs around 299.99-319.99 around here and that thing is one sweet performer.
I hope this has helped.
