Homebrew PCBs

I am interested in doing some photo etching of 0.01" brass sheets 
that are 4x10", and I would like to try the TT method of transfering 
my image to brass.  Note, these will be etched on both sides, and 
this would not be for pcb purposes (but for art's sake).

There has been lots of discussion of laminators being used with 
better results than an iron.  My question is this:

Is there a brand or model of laminator that can be had that generates 
sufficient heat to do a transfer?  Or is there a model/brand that is 
easier to modify the thermastat for higher temps?  I can get a 4" 
laminator on ebay for ~$1 plus $10 shipping (GBC HeatSeal H100 Pro).  
The thickness of the brass translates as - 0.10" = 0.25mm (thinner 
than pc boards).

I would have gone ahead and used the iron method, but I'm afraid that 
the thin-ness of my material and the fact that I'll need to iron both 
sides scares me off.  I don't want to iron one side successfully, 
just to ruin it when I heat the other side.

Any thoughts?
