silkman, here a few facts...
a) The default cap is set at 3gb, until november the highest you can get is 30GB
b) Once capped you will have virtually nil international access, maybe, just maybe 3 KB/s, local speed is unaffected
c) Upload and download contributes to your cap
d) In november it is estimated for pricing to be round bout R75+- excl vat per gig and when capped then you will either buy more bandwidth or be hard capped.
e) anything non ftp/http is heavily shaped for international (p2p and games)
3 gig account set you back about R250, 30 Gig acc R200 with webafrica if you use the myadsl forum promotional code (this only lasts till end of october) otherwise bout R350 with axxess.
Backbone wise some of the ISP's you can try are...
SAIX: axxess, webafrica
Internet Solutions (IS): eastcoast access, gamco
DataPro: DataPro
DataPro will slow you down in november to about 4KB/s when capped in november.
SAIX will lock u down completely
Internet Solutions is unknown to what they are going to do.
Were I getting adsl this instant I would buy a 1 or more 30 gig acc's from webafrica with the promotional code since it would just be R200 per acc then, this month and next month then see which ISP has best to offer for november.
