Reply to Djm-500

I have been looking for a decent 3-4 Channel mixer. I would love to pick up a Pioneer 800 but don't have the money I will have about 300 in christmas bonus money and I recently found a DJM-500 on Amazon for about 400 bucks.

Do any of you own one? Would it be a good beginner mixer? I am a huge fan of Pioneer build quality and resale value. My other option is a DDM4000 which I would be happy with but call me a fan boy I love Pioneer products. SO what's your opinion should I get the DDM4000 or save a little more and get the DJM-500 or save a few more months and get a DJM-600? Thoughts?
