It is good quality for the money - what means expensive?! My advise is buy
good hardware - and it is usually the business line.
The Dell 5440 was around US$900,- and I considered it cheep (incl. docking
station in 2016)
The ProBook is 645 G1 also great.
No touchscreen.
Latitude 3190 2in1 starts at ~600,- (589,00 €) with touch screen.
Similar for HP (Elitebook although I liked the ProBook better).
