Double Sided Aluminium Dry fly box

[Surfacefisher]

Hi,
Does anyone out there know of any manufacturer other than Richard Wheatley who makes a Double sided aluminium dry fly box with individual compartments which have spring clips on each of the compartments.
The box I am looking for is identical to the Richard Wheatley Model 1609 but at £100 each I was hoping there was an alternative make.
I have came across many similar boxes but most have only compartments for dries on one side and either foam or clips on the other.
I need to purchase three of these boxes but don't fancy paying £300 for them.

Other than Wheatley have never seen another company that do similar double sided compartment.
Okuma & Snowbee are the ones I think of but single compartments on one side only
Why does it have to be double sided? would single & say a foam side not do?
Stateside would be you best chance if there was such a thing.
