Theres another one on ebay
I want to add my experience with these thing some more.
One of the major complaint about these laptops is the fan noise and the heat. The fan can be manually controled with TPFanControl. Make sure you patch the fake error reporting.
People complained that heat sink is inadequate. on t43. Id reccomend not going CPU higher than 1.8 I put the 2.2 ghz in one of mine and its fast but its just too much. There is also no heatsink on the south bridge and its right under the wifi. I never had a problem with it but I considered removing the internal wifi and using a pc card for wifi.
T41 with the ATI Mobility Radeon 7500 seems to be about the sweet spot for win 98se, If you take the heatsink off a t43 and put it on a t41 with a think termal pad or shim on the gpu I think that could be good.
The ADI AC97 does have soundblaster emulation, but your results may very. You can set environmental variables and it should work.
