I have quite a bit of Beta, picked up a bunch in the brief period Amazon was stocking them, and then have imported a bunch over the years.
They have a few standout tools, namely the P-handle hex keys which are fantastic. Everyone throws praise on the PB Swiss, I think the Betas are better (I have both). If you believe them, they're the only company other than PB Swiss that forged tips on their hex tools, even the venerable Snap-Ons are extruded. Their screwdrivers and pliers are also very good, ergonomics are second to none.
That's kinda where it ends though. Their wrenches are good but nothing outstanding, their sockets aren't bad but aren't great either. The ratchets are probably their weakest point, lots of backdrag and the selector switched completely flush, which makes it hard to change direction.
I haven't sold any of it and it still all lives in my tool chest, the P-handles, pliers, and screwdrivers are the only things I reach for first. The rest I could live without.
I did pickup the tool trolley as well recently, which you'll see littered around the MotoAmerica paddock. It's a great trailer box if you're a trackday/racer type.
Also, be aware of the difference between their Beta brand, and the Beta Easy brand. The Beta Easy stuff is almost all made in Taiwan, and is priced lower to suit. They still make all the hard goods in house in Italy, from what I understand (wrenches, hex tools, screwdrivers, sockets, etc.).
