Best GPRS deals from UK network providers?

[Guest scrattyrat]

Hi,

does anyone have any suggestions for which network (UK) gives the cheapest / best GPRS deals (either inclusive in monthly tarriff or as add-ons).

My current deal is finished next week and am going to a new provider for free handset. As im looking to get a smartphone - and hope to be doing some internet browsing I'm anticipating high GPRS use - which is not always very cheap.

For all you smartphone experts how much GPRS data does low to average internet browsing tend to use up (ie 1-2 web pages per day?).

Thanks,

John :D
