Like Tracy says, it really isn't worth financing on it, the interest rates are horrendous. The only option for financing is through Disney, there used to be an option to finance through a UK company (GE money) but not any more.
We initially took finance because we had to buy while we were there (in Feb 2007) but didn't have the money to pay in full until October 2007. Definitely better if you can pay in full.
You need to do your research, though, it is a huge outlay and not one to be taken lightly as you have the ongoing commitment of maintenance fees. Buying resale may be the way to go but you need to understand the restrictions with that too.
In order to answer your initial question, we paid $105 per point but got an offer of a $15 per point discount, making it $90 per point. We were able to offset some of the discount to use as our deposit (meaning we financed slightly more) but all in all we ended up paying around £10K.
