Best value DisplayPort splitter?

So I have a Dell Latitude E7440 laptop with graphics powered by the IGPU of a Intel Core i5-4310U Processor (I think an Intel HD 4400). The laptop has a Mini DisplayPort out that I want to split and output to two 24in monitors using their DisplayPort inputs (the DVI inputs of the monitors are already filled by my tower so running a mixed HDMI/DP set-up on the laptop isn't possible).

First question is, are there any good DisplayPort splitters for a reasonable price? And is it possible for said splitter to run two different resolutions? (One is 1200p and the other is 1080p).

Any recommendations are appreciated!
