I'm far from an expert on that model, so I can't comment about it's reliability, but I'm not impressed with the price. For around the same price you could buy a new tractor that will have more power, a lot more FEL capacity, and lift height, more standard features, and a warranty (among other things), but you probably couldn't fit the rotary cutter in for that price.
I'm not suggesting you should buy any particular brand, but I know my local dealer is selling LS G3033s for right around $15K (advertised is slightly higher, but they'll normally come down a bit). A machine like that would give you the same basic size, same weight, more power at the PTO than the Deere has at the engine, the same 3pt lift capacity, almost double the FEL lifting capacity (to 5" higher), 3pt draft control, telescoping stabilizer bars, similar hydraulic pump flow, and a 5yr warranty. I think you could get a Kioti CK for about the same amount of money. Here's a local ad for a 3033:

I'm always a bit concerned when I see a 10-11 year old machine with just 200 hours on it. That means it either averaged 20 hours a year, or was used a whole bunch for a year or two, and then sat around, and the owner finally decided they don't need it. Neither scenario is really the best for long-term reliability. Machines last longer, with fewer problems if they're used regularly, and that's hard to manage with only 20 hours a year. Inside storage helps, but it's not a complete cure.
As far as the weight, I think the difference between Kubota and Deere is mostly a design philosophy thing. Deere is grounded in U.S. style agriculture, which means big fields, big machines, big implements, and for those, more weight usually means better traction, and better productivity. Kubota is grounded in the Japanese/Asian farming market, with much smaller areas, where size/weight can be a drawback. Whether more weight will be helpful for you is really hard to say. It's hard to make the machine lighter, but adding more weight is usually fairly easy (not always cheap). If you're using ground-engaging implements, weight usually helps, but maybe you have wet areas, or a small bridge to cross where weight is a negative…no way for us to know those sorts of things. Generally speaking, I think 2,500lbs is a pretty common weight for machines with that size engine…which tells me it's probably a good reference point, if nothing else.
