IINet vs Exetel - is it worth going naked? Maybe not...

I currently use the ISP IInet using the 10GB Off Peak/10GB On Peak (ADSL 2+ light) package. However, I have heard a lot of buzz about the so called 'naked' plans available through IInet and other ISPs like Exetel. Up till now, I grudgingly needed a phone line just for ADSL. To me that was $30 bucks down the drain.... until now. The naked plans don't require line rental at all!

On the face of it, I prefer the IInet deal over Exetel for my situation because:

1. IInet have been a great provider so far and there are some rumours about Exetel having a less than stellar approach to customer service.
   
2. I already have a Belkin router (F1PI241ENau - http://catalog.belkin.com/IWCatProductPage.process?Product_Id=247190) and have heard that they don't play well with the Exetel service. I don't want to fork out $200 for a new modem that works with the Exetel naked service.
3. You get an incoming number as part of the IItalk service. Apparently you have to pay $10 extra to add this functionality with Exetel.
4. Even though uploads are counted as part of your bandwidth allowance (Exetel doesn't charge for this), I don't upload that much ( about 1GB per month ).
5. I don't really care about having a static IP (this is what Exetel provides).
6. P2P are shaped (according to official announcements) on the Exetel network (see http://whirlpool.net.au/article.cfm?id=1734&show=replies )
7. No excess usage charges (just shaped) - wheras Exetel charges $3 per GB.

However, after considering some of the drawbacks (e.g. measured uploads including voice), I am staying put for now to see where the new naked DSL market heads.
