The "standard" resellers will all offer the same speeds, as for CS, it's pretty much a level playing field.
This subforum, is where a lot of the resellers, and indeed the Entanet reps hang out. The speeds
may vary, if you choose an L2TP reseller, as they can implement their own QOS, should they feel the need to do so.
Aquiss, Freeola and Xifos are, as far as I know, L2TP resellers. Standard resellers, don't implement any kind of QOS, as it's all down to Entanet.
