I am trying to build a laser diode driver circuit which which should give a required output of around 1.25v and 200-250mA, I have been having problems with this and want to start inspecting it with a multimeter. The only problem is, I don't have one and really don't know how to select the correct one for my application. The laser diode driver circuit I am working on is the following:

Please note, this also includes an NPN transistor within the application. I would also like to use this multimeter for analyzing future projects which include large stepper motors such as the Nema 23 (270 oz) stepper motor.
The multimeter that I have been looking at is the following:http://www.ebay.co.uk/itm/VC99-6999-auto-range-multimeter-tester-Amp-C-Tcompared-FLUKE-analog-bar-UK-ship-/121074199075?pt=UK_BOI_Electrical_Test_Measurement_Equipment_ET&hash=item1c3095aa23
Would this be "fit for purpose" for my requirements?
