A4000T doesn't use a rechargeable battery, it uses button non-rechargeables so no corrossion is possible.
-A4000T SCSI controller is much better than A3000T too.
-A3000 doesn't have IDE controller.
-A4000T uses simms instead of expensive and hard to find ZIP ram.
-A4000T has AGA (useful for Scala, video stuff, games and demos... and you can't add AGA to an A3000T no matter how much money you invest)
-A4000T could include Quickpack 060 fast accelerators OOTB
The only advantage of A3000T is that it includes FlickerFixer. And that's all. Not a big problem as you can connect internal cheap scandoublers/flickerfixers.
If you can live without video stuff, games and demos you'd better switch to a next gen solution like Pegasos/Efika or Sam440/A1.
For me AGA is important. I own heavily upgraded A3000, A4000, A4000T... and I prefer having AGA. You can't watch most of demos released after 1994 on an A3000.
