Paul hope you have one as your gonna need it for the ff imp your getting, i know you are interested in getting the i-frame but take a look at this...http://www.impulseownersgroup.com/vb/showthread.php?s=&threadid=5214&perpage=15&pagenumber=14
You might have to register but it is a good forum for answering imp problems anyway. i have been following it and it looks pretty good, if you are shipping from the states anyway maybe this would be an idea, It's only $100 and certainly looks good would be different from everyone else too!
watch the video, a bit fuzzy but you get the idea!
If you do decide to get one i might get one or two as well ( just to play with) and maybe we could split the shipping? I dunno just an idea.
Mail me if you have any ideas.
