LLU providers available on my exchange:
AOL
O2 / Be
C&W / Bulldog
Orange
Sky / Easynet
TalkTalk (CPW)
Tiscali
Tiscali TV
If you don't mind buying your own router and paying an activation fee, then Xilo's Pro 16 O would be a great choice for you. It runs over C&W LLU and is incredibly good.
If you don't want to have to fork out extra for a router or activation fee, the BE is the best choice.
With that many LLU providers on your exchange it makes no sense not to go with an LLU providers.
See the stats and speedtest result in my sig to see what Be* can offer me. The ping times and throughput never fluctuate, there is never contention or traffic management, and no download limits.
The only IPStream option for you would be IDNet Business Premium at £80 a month. All other IPStream options (including ENTA.net) are Traffic Managed and / or Capped with a download allowance.
By the way, why do you state you want to be with an IPStream provider? The IPStream network is far inferior to most LLU networks, after all...
