Some help with spending money! need flash kit

[mucca_D]

Gents,

I have been given by my wonderful company £250 to go an buy a flash set up.

The reason for this, is that the Camera club have been asked to do photos for our Xmas party ( black tie) and I said we would love to, but would require some kit. So I now have £250 to spend on this.

Now if it was only for my Camera I may be tempted to buy another 530, but not all the club has a canon etc etc ( not that it matter with manual and wireless I suppose)

The consensus of our group is to go for a kit, and it makes sense if people are using it from one site to another.

I have looked at Interfit Studio Lighting and the Interfit EX150 Mark II - 2 Head Kit looks a good setup with great reviews.

Then I looked at the Interfit Super Cool-lite 5 Twin Head Kit.

so;

1. Do you rate these?
2. Is constant light better than strobes?

Would anyone recommend something different and why

Thanks in advance for your help

Doug
