Damn, I wish you'd provide a link to that Scotts thing.  Best I could find was 
this John Deere.
No doubt, I'd pass on Murray for sure.  I think N8Magic is right.  I'm a little perturbed that Snappers are no longer able to store standing on end.  I bought my Wheel Horse 111-5 speed back in 1986.  It was targeted at the Snapper and 
Ariens riders.  The Ariens does still have an  
Upright Service / Storage Position, which is very nice.  The Snapper can stand that way for a short time, but you have to drain the oil for storage.  Both the Snapper and Ariens use a crude 
Disc-O-Matic Drive System.  That system has been used by them for decades and is tried and true... but crude!
I opted for the Wheel Horse because of it's Peerless 5 speed transmission.  The same type of tranny used on some garden tractors!  I also like the way it's discharge chute came out the top of the deck, instead of the side.  That way I can trim on both sides of the deck.  The model was discontinued when Toro bought Wheel Horse a few years later.  I just put a new Briggs engine on last fall, so it's like new again!  That's 16 years of use so far and I expect it to last at least that much longer.  It cost $1,650.00 back in 1986 including the rear bagger.  When the engine died, I looked into buying a new Snapper.  It would have cost $2,400.00 for a 
33", Kohler model including the bagger.  It bugged me that I couldn't store it upright, so I looked into fixing mine instead.  So glad I did!
It's important to get one with a large single blade instead of multiple blades.  The single blade has higher tip velocity for throwing wet grass or leaves all the way back into that bag.  Get a demo on a Snapper, Ariens, and maybe even Yazoo.  You'll be money ahead if you can buy one and keep it a few decades instead of buying a new one every five years or so.  For that reason, it's a good idea to buy a brand that keeps parts for their old equipment.  Snapper fits the bill there!
