I'd avoid the TJ... I didn't even know they made loaders. I can't imagine that support would be great for them today given their probable production numbers and the fact that it's owned by Deere today.
The Volvo's have been around here for 25 plus years now as either Volvo or Michigan branded loaders. An L70 would be in the price range of that Dresser you're looking at. In terms of wheel loaders in this area... Michigan/Clark was long the standard so when Volvo acquired them they more or less brought the business along. You either had the Cat guys or the clark guys... and still do. There's always some others around but Dresser/Komatsu are kind of an orphan here. I'm sure they're a decent enough machine but there's just not many around. Cat is probably a second in wheel loaders here in the utility size market compared to Volvo.... while Cat has the large market for the most part. Volvo's were the first in this area with good 4 speed auto transmissions, LONG life engines and tight nimble hydraulics. If you have a good presence out there with Strongco... that's the way I'd be leaning if I could find one reasonably.
What I would probably avoid is something like the old Ford loaders.... A-62, A-64, A-66. Not that they're bad loaders.... but their support is sparse today. A lot of stuff in them is common components and what you see in the parts system is the goold ole' 'procure locally' which boils down to a wild goose chase...
I'd avoid some of the ancient Cat stuff too as some of their parts support is starting to get thin.
