I just found that the hottest WinMo HD2 was on T-Mobile at Combi 15 deal.
You just pay £195.73 first, then £13.5 per month for 18 months
It works out as followed:
£13.5/month*18months + £195.73 instantly paid = £438.73
This is the cheapest price for the HD2 atm and you don't have to pay the full price.
100 mins and 100 texts are there for fun every month and Quidco will be tracked for £20 as well. Probably £418.73 after all. This sounds cool to me. Hope this can get some heat.
**ADDED: My Quidco was just tracked for £40. Hope they don't change their minds later on.
