Hi mate,
send me a PM letting me know exactly what unit your after... i'll see what kinda pricing i can do for ya. Then we'll look at the shipping costs, then i can set it up on ebay for ya with a buy it now option or just a really short auction or something, but you'll have to cover the ebay seller's fees as well...
we can do it without the ebay bit if you want but as you said you want some security and i can completely understand that.
Cheers,
Dave.
