Re: It's been years since . . . .
TP-Link TD-W9970's are worth a look, change out of £30 ex VAT. Years ago I'd considered TP-Link budget, I suppose the prices still are, but the software on those is half-decent. Do IT support for small business; they suit them fine, and can be popped into bridge mode and used as a modem easily for places with a beefier router in place.
Used to carry separate ADSL routers and those white BT things a few years ago, now a couple of those in the car pretty much covers all the smaller sites.
No doubt someone will pipe up that they're a load of dung, but reliability-wise haven't ever had an issue with one - for the money they're great.
