There’s a lot of info on that in the forum.
the Handy is the most popular device partially because without doing DIY engineering it’s the best device on the market.
There’s a bit of debate on whether you should get the Handy now or back the kickstarter for the Handy 2, which you can check the forum’s affiliate for in the banner.
Lots of people are anticipating the new handy. My personal advice is to probably back the kickstarter and get a handy 2 pro or standard. you can see lots of info in these threads:

The original handy is still a great device if you’d rather not wait.
