If you have the trailer space an moeny ide go with individual tools.
If you dont I would go with the stihl combi. Go with the pro version not the HO version. I have a buddy who runs a stihl pro version km110 an it works great. He has had it a while an I use it sometimes, absolutley great machine for a multi system. He swears by it.
As far as price Sometimes you get what you pay for. If you want dependable equitment you have to pay for it. It will save you alot of moeny and hassle in the wrong run if you just get the right equitment the first time around.
