I've been researching these "two wheel tractors" from Italy a lot lately. After seeing them first hand its a no brainer. I don't want a used gamble, so I'm looking new.
A new Big Red is not cheap at all, at $2600 its actually about the same price as a Grillo 85D that has an industrial Honda, all gear drive, a slick differential equipped axle, fully adjustable handle bars that go up and down plus side to side. So, you can rotate the bars for walking beside the machine. The BCS have the same features plus an instant reverse lever, but for the refinement you pay a good bit more.
Comparing prices and features I think the Grillo G107D is the best deal for me. Its just under a BCS 853 in ability, but its about $1,000 less for just the tractor. With attachments the no steering brake 739 BCS will run me at least $1300 more than a Grillo set up. The Grillo tiller is more to my liking too. I figure the 11hp 107D would make more sense, I could spend the $1000 on a brush mower and still be under the cost of the 853. I've talked to people who own both brands, they are well liked. Either way, I'm going to deal with Earth Tools or one of their dealers. I rather deal with a properly set up machine.
I could get an older Troy-Bilt but, I use my tiller weekly most of the year plus I'll get more attachments for a Grillo. I don't need another unknown piece of used equipment. I have plenty to keep repairing already.
I have a good Kubota L4330 tractor with a rototiller, hipper/row maker, disc, bush hog, bottom plow, cultivators, subsoiler, middle buster, box blade, back blade etc. But, I use the walk behind tiller to cultivate in the tight spots and I have multiple raised beds and other things to cultivate. If things keep going as planed I'll have a solid market garden operation. I'm getting my rows tighter so the tractor can't get in as much now. I'm also mixing in soil builders as I can, enlarging the garden areas more every year. Its enjoyable to me.
