SDS Hammer drill - Go cheap or branded?

[mattylondon]

I have few more demolition jobs around the house, especially an over engineered blocked fireplace that I'm reopening for a woodburner, and an SDS hammer drill with chisel would be a great addition.

I'm thinking of going cheap. Such as this one

And if it dies after a year or so that's ok with me.

Or are their any merits to go with a branded Hammer Drill, like this one?
