Sorry Bambi - you asked about more upstream. If you want more upstream you have to go to the business products. SDSL from sunrise 1200/1200 and 1800/1800 at 419 and 519 per month respectively. Cablecom: 3000/800 and 4000/1000 are 220 and 390 respectively.
A bit pricey unless you have a really good reason for that much upstream. The server that runs this site has around 50 domains on it and usually uses around 500kbps (but it supplies a lot of downloads for one particular site). Without that site it would use 50-100kpbs. I have 100Mbit available though
Apart from improved bit torrent ratios I can't see much point to go beyond 400-500Kbps on the upstream.
