Proprietary Trading:Money Grabbing or Helping Traders??

Anyone had a taste of the Prop programs out there? such as Pristine

Oliver Velez's http://ifundtraders.com/
Trading advantage http://tradingadvantage.com/how-to-trade/index.php/tap
plus the myriad of others

1.Have you undertaken the program-how long ago??
2.Are you making money?
3.Are the promises(pay outs) adhered to or is there shifting of goal posts??
4.any other recommendations

Thanks
