Does anyone know of an off-the-shelf adaptor from a TQFP64 ZIF socket to a 64-pin DIL plug, suitable for connecting a Mega128 to a DIL breadboard?

The ZIF socket needs to be a positive action type such as that used on the STK501 - I had an adaptor made two years ago using a "clamshell" ZIF socket, but it was so unreliable as to be useless, and ended up burning out the board when it shorted together the power pins (which are unhelpfully adjacent on the Mega128).

I may be able to get another custom adaptor made, but it would be a lot quicker (and presumably cheaper) if something suitable already exists.

Both http://www.Kanda.com and http://www.Olimex.com make carrier boards for the AtMega128. http://www.SparkFun.com is my prefered distributor for Olimex products. Both leave something to be desired.

Unfortunately, neither of these have ZIF sockets and neither connect to 64-pin DIL plugs, so they could not be used on a DIL breadboard (which is made by Kanda, as it happens).

I already have a Kanda adaptor with an old Mega103 chip in it. I considered cutting off the Mega103 and substituting a Mega128, but it would then be difficult to replace the chip if it was damaged, and I could not use it to program chips for use elsewhere. I would also have to hand-wire the 64 pins to the breadboard - exactly what I am trying to avoid.
