I agree but you only have to do it once and the longer you leave it the bigger the job gets.
However, there's no problem in running an ISP and non-ISP address side-by-side so get your independent address first and then take as long as you need to register your change of address with whoever needs you want to know your new address.
For extra advantage register your own domain which allows you to switch the MSP if need be. Since ditching my ISP (Nildram which was fine until a series of take-overs left it in Dido-land) I've switched not only ISP twice more but also switched domain registrar/MSP (ending up with Mythic Beasts and see no reason to swap again).
