Mock exams which is better?

i found three mock exams for 310-052 Part 1
1) Whizlabs
2) Epractizelab
3) ePractice: Sun Certified Enterprise Architect for the Java Platform, EE5

Which is better? any other?

I used whizlabs - it was ok. Atleast it didnt have ridiculously worded questions like another one I had used for SCBCD. But mostly they had copied from sun's mock exams. I got them free when I purchased the actual exam. I would say the sun mock exams are good. Once you have done couple of them you should be good to go.

Thanks Sivan for reply,

i have heard lot of negative thought for Epractizelab, so not sure weather i will buy it, but i am sure going to buy Whizlab.

I have been using Whizlabs SCEA stimulator. I am not satisified with the question pool. When you repeat the attempt, the questions are all the same and in fact the order of question and answers is also same. Its like you can blindly appear for subsequent attempts and get 100%.

I would not recommend Whizlabs SCEA stimulator.
