Routers n shizzle Options

[Qrbrrbl]

So im looking to upgrade my current router. Its an old netgear model which is two slow for me now both on the wireless and ethernet front. Heres what im after:

Gigabit ethernet capability, 4 ports at least
300mbps+ Wireless N capability (not bothered about dual / single band)
ADSL modem

Im getting confused by all the jargon to be honest. From what I can see, most gigabit routers out there in my sort of price range (sub £100, as close to £50 as I can get) dont seem to include DSL modems? I dont have the power sockets to have a separate router / modem and I definitely need both gigabit ethernet and high speed / long range wireless.

Any ideas?

I did look at the buffalo briefly but it had poor reviews on range and speed from what I could find. in any case, I've eventually gone for a separate ADSL modem and wireless gigabit router. the TD1043n off the top of my head. it does the job and means if / when I upgrade to fibre I only need to swap the modem, not the whole thing.
