We've had one for donkey's yonks and apart from blowing an O ring just as we started haymaking one year, it's been relatively hassle free. Mr F tends to replace parts with Brit equivalents for quality, but for its price it's great. It isn't big enough to operate the baler and so on, but we have an ancient and very decrepit David Brown for that, which sits idle for most of the year.
Ours was one of the first in the country, so when it was delivered the chap helped us put it together to the point where we just had body work, wheels etc to finish. You don't have to be an agricultural engineer to get it going. Originally we got it for me as I'm not particularly tall, so my feet don't reach the pedals of the DB
Spares come through quickly if you need them, and when we decided we needed a front loader we popped it on a trailer and took it down to wherever it is near Blackpool, then discovered the best cake shop in the world at I think St Ann's along the coast. Made the day worthwhile. In the evening we drove home again to Scotland.
Implements we went for are rotavator, single furrow plough, roller, back box - I think that's it. It fits the rake we already had ok and tows the sheep trailer.
It really depends on how much spare cash you have - we had hardly any so went for the kit Siromer, but we've never regretted it - except that O ring
We use it on a fairly small acreage and I can't say what it would be like with heavier usage.
