Let me tell you what I know abt VXL.

-- VXL is not a consulting firm. It is a training institute buut it woks in collaboration with a lot of consulting firm. So, their strategy is that they will give you training and then pass on to some other consulting firm. In that strategy VXL will not ask you money (i might be wrong) but the consulting firm who VXL will pass on will take off the money from your salary once you get the job.
-- VXL usually provides living cost. They will pay your fooding bill too.
-- Training is not bad, can't complain about their training.

so, in conclusion -- its not a bad option ...but be cautious.

hope this helps..
