another Stihl brush cutter thread - FS240 vs Kombi

[newbury]

I've got a FS250, like it. My son's birthday is approaching and he requested a trimmer/brush cutter that can also do tilling w/ an attachment. Presently he's got bamboo to cut down and a few raised beds to till (nothing big enough for my 5' tiller), plus regular grass trimming.

Now the FS 250 is no longer for sale and has been replaced by the FS 240, but it's similar and will take a mini-tiller attachment. The other thing I'm looking at is the Kombi 130 system. Price and power seems to work out close for either system.

Any recommendations one way or the other?
