I have the Studio. It's not the weight of the machine it's the shape too. My husband and I carried into my space together. Could I have moved it myself? Probably as I lift heaver things. But, the way the weight of the machine is distributed would have made it awkward and maybe dangerous. I bought mine used, and I've not had a single problem with it in the several months I've owned it. I have never heard of a single problem from Studio owners. Since I bought it used, I don't have the life time warranty. But at least any new dies I buy will have that. I've never regretted spending more on it. Much sturdier than the Go and won't break on you.
