@W3bbo: Some of them like the MCTS and MCSD are highly regarded. In fact if you have this certification and work in a Microsoft Certified Partner company, you will usually get between 5 and 10 thousand pounds extra on top of your salary compared to staff with just degrees. There is no harm in continuing to add certificates to your portfolio.

I also think you should pick of one or two copies of the latest and see of you think you can sit the test in 2 days, you will find however that you have to do some studying.
