Any recommendations for a flash for the X Pro-1?

I bought the EF-X20 because at the time (before the latest firmware upgrade), people were reporting problems using the EF-20 with the X Pro-1.

I do like the external controls of the EF-X20 and it suits the styling of the X Pro-1 nicely but it seems very over priced for what it is.

If I was buying again I might go for the EF-20 instead. Not entirely sure though. Given that the EF-20 is a lot cheaper I might just get one of those as well and have both options.

Cheers

Darren
