I'm an advocate of not paying more than you have to .. I'm also an advocate of paying as much as you need to.
A bargain isn't a bargain if it doesn't do what YOU need it to do, just as much as a high end unit isn't a good value if it does things you don't have a need for.
Buy right.
I'll add one more:
Brand and Price are not what makes a unit high-end, they are merely consequences. Don't assume something is high end simply because the marketing department raised the price and started printing brochures on glossy paper.
