I am using a zyxel vmg1312-B10a as of yesterday which just replaced my HG612, there are others in the zyxel range though and most kitz users seem to be using them.
I’m currently using a Vigor 130 on a ECI cabinet. Though I am bidding on a Zyxel VMG1312-B10A, mainly just out of curiosity to see if it’s any better on my line. Wouldn’t particularly want to spend the £100+ they seem to be new though.
If you're looking to buy brand new and at a reasonable price, then also consider the Netgear DM200 and TP-Link W9970. They're priced around £30 on Amazon. The TP Link uses a decent broadcom chipset (same as the Zyxel model(s)) whilst the DM200 uses a Lantiq VR220, which is also decent.
