[papeter]

Please could you appraise this four letter dot com. RCFU.com
I thought it could represent Radio Controlled Flying ???
Anyone any ideas what the 4th letter might be.

I also have BUNH.com I get $200/300 offers from china on this one.
I am sure it should be worth more.

Thanks Guys

$300 is a fair liquid price now.

End user may pay $10,000 +
