Flail Mower Kubota FM120 4 foot flail mower - any good?

[biffo]

Has anyone used or have an opinion on one of these Kubota FM120 4 foot flail mowers, or maybe used one ?

I have been offered one of these with less than 30 hours use, it's a bit pricey but Kubota quality, so as I am in it for the long run it may be worth paying for the name?

Thanks
