I bought my ADSpeed ST from Toad for about $200.00 a couple of months
ago.  I haven't had any problems other than a few programs not being
able to run at 16 MHz.  I've got the jumpers set so my ST boots up at 8
MHz so all my old game disks will still work.  The software they supply
lets you change speeds without re-booting.  There are several methods
you can use to change speeds:  stand alone programs (for use in your
AUTO folder or via a program launcher like HotWire), assigning a hot
key, via a desk accessory, or via an optional hardware switch.  I like
it when a company lets you choose your own preferred method of
operation, rather than forcing one upon you.

Installation involves de-soldering your existing CPU and soldering in a
socket for the daughterboard.  You also have to solder in a jumper wire
if you have a Mega ST.  The daughterboard even has circuitry that
duplicates the functionality of the existing Mega daughterboard.  Then
it's just plug 'n' play.  It took me about an hour.

I bought mine so the MIDI buffer in X-oR wouldn't overflow when
processsing a large System Exclusive dump (the data processing routines
just couldn't keep up at 8 MHz).  It can now keep up most of the time
(unless I have Warp 9 installed, which seems to move the MIDI interrupts
to a lower priority).
