Man, I don't want to get reamed for saying anything negative about Yamaha but if you're looking to ditch bang and stay in that price range, consider the past "snocross" type sleds. The Yamahas of that era might not be the best choice - the Nitro of recent years is the closest but you're talking a lot more money. I think the Cats had a good set up for that time for that style. Doos were ok but still had the trailing arm on most. Both had less weight than the SRX.
I mainly run Yamaha (sleds, quads and bikes) and have had a still have a lot of them. Like many other Yamaha loyalists, I have been frustrated with the lack of a great boondocking+ditch banging+trail sled in their lineup. Ski Doo's late model Renegade seems to be the choice sled now - and it shows in the resale values. I work on lots of sleds and will say that overall, Yamaha pays a lot better attention to detail than any of the others. All the manufacturers put out a good product - otherwise they would not be in business. If you are able to do so, get out to the sledding stop over places and strike up a conversation with riders. Some might talk up their sled but you can see what the predominant type is for what you might want to do. Also, any sled that has had heavy use for ditch banging is going to pay the price.
