Probably the same L50G I was interested in, sitting in Grand Prairie? Has had a problem with that transmission in that 381 hrs, and is currently leaking, once it has a new owner they will replace it under warranty. I was very much interested in it but decided on an L60G instead, as I wanted to jump to the bigger frame size (handling big squares, some contract work). That L50G doesn't have the high speed option either.
I've ran a CAT (938G) and a Deere (544K) at work, and drove a Volvo for the first time last week, though have always been looking at them. In my opinion, after running the Volvo it would be hard to purchase anything else.
Huge benefit of the Volvo to me, even if you don't care about the comfort, is the boom design. It's a hybrid of sorts, combining a tool carrier and a z-bar. It is the same boom design from the little compacts right on up to the huge mining loaders, so that should say something about it's versatility. Cat finally same out with a similar setup with the K-series as well, to eliminate the IT series (integrated toolcarrier). Boom suspension has 3 settings ([dig/grade/off], yarding, and roading. I can see my quick attach, I can see my pallet fork tips at all times. Nicest cab on a payloader, ever. Smoothest ride. Best visibility in all directions, even behind. Volvo has a park brake on the dash, a toggle switch. I hate emergency brake levers. We have them in 2 tractors, we all get in and drive 5 feet before realizing its on. Now you need to crank them tight to get it to hold the tractor. Park brake is nicer in my books!!!
Deere has 4 different booms that I'm aware of (TC,24,44,24HL). TC is a tool carrier machine so it looks like the front end loader on a tractor. Designed for pallet fork work, capable of bucket work. 24 is a non-parallel linkage, where-as the 44 is. And they have a high lift option. Deere doesn't have a universal quick-attach, it's basically like excavators where you can spec it with a few different common styles. The Deere 544K, I can't see my quick attach, I can't see my pallet forks. Vibility is TERRIBLE as far as I'm concerned.
Cat is probably worse than Deere, they can't make up their mind on a boom design either, changes with each new series, and from size to size. On their mid-size (924-938K they came up with a universal hybrid design to have the same benefits of the Volvo. Cat K-series cab probably rivals the Volvo, but that's new and Volvo has had it for a long time. Volvo has room for two people, don't believe the CAT does. Your kid gets to sit on the emergency brake (used to, new K-series has park button like the Volvo now).
Case wouldn't even be a consideration to me, I've talked to too many people that have owned them, were die-hards all through the models, and now the last few generations have lost all reliability and durability.
I'm not sure, but the L50G may accept the attachments for the bigger machines as well, in case you want a big snow bucket or bigger forks, etc.
