Re: [IRCA] Supercharging the XHDATA D-808-- Full Construction Article

[Guy Atkins <dx@xxxxxxxxxxxxx>]

Hi Gary,

This is another great write-up as usual! Thanks for taking the time to
document your hot rodding of the D-808.

If I recall, weren't you also one of the initial USA purchasers of the
D-808 as I was, for a bargain-basement price of ~$68 USD, shipped? A seller
on Aliexpress.com was offering it for this price. Mine came promptly and
was very well packed for transit from China. Not long after this, the
phenomenal $68 price disappeared; hopefully the seller didn't "disappear"
also  :^(

It was after this early, very low price was yanked that we started seeing
ridiculous offers on the D-808 ("just $75.00 + $500.00 shipping", etc.),
until the situation settled down to the current $112.87 + $10.00 shipping
to the USA.

BTW, I don't know why but I've tried downloading your article more than
once, but only the first half of the article appears. It ends just after
entry "J" under Construction Parts.

73,
