School me on Skid Steers

[M16]

I've always been a tractor guy but need a new toy. I'm leaning towards a skid steer. What are the brands to stay away from? If you don't get a mulcher do you need a hi flow machine. I'm still undecided if I really need a mulcher. If not I would get a heavy duty shredder brush wacker. What about horsepower? I've got a couple of thousand acres to play around on. Mainly to be used patching roads and doing brush control along the roads. What are the attachments that you can't live without? Would you buy new or slightly used? Budget is going to be around 100K.
