Find me a residential ISP that guarantees quality of service will achieve maximum at all times, or indeed a business ISP and I'll be happy to look at them.
You share bandwidth with a number of other users, sometimes there's not enough to go around, that's why your service isn't over £100 a month.
As said previously there's no point in your maximum upload being increased if congestion is holding your speed down..
Not that you'd get a customised service all to yourself anyway, no ISP can allow users to choose their own speeds at the moment, you are offered a defined set of tiers.
Just out of interest, if upload is so important to you why are you paying Telewest £35 a month for 2mbit/256k when 4Mbit download 512k upload with Bulldog along with line rental is about £40 a month, even less with the special offers? Telewest offer a 384k upstream on their 4Mbit service as well don't they? Seems like that deal would suit you better, even if it would *horror* perhaps cost a couple of milliseconds on ping.
Sorry is just weird you complaining about how important upload is with you, yet you neither take the highest tier from your current supplier upload wise, nor do you have what would be the best option available to you upload wise. Odd.
