I'm afraid I have no personal experience of the D-link 2740B so I cant really say.
My past experience with d-links hasnt been the best - but thats more firmware stuff.. but I believe that d-link have pulled their finger out and are actually providing better routers these days.
My own opinion of the TG585v7 is not Good...
I had a brand new one.. which I think is now completely useless - I need to look at it properly to see if it is well and truely dead, or whether it just needs a "rest" - it blew last night. The one I had was using the standard ST firmware - not the Be one, but from what I gather, its a cheaper chipset and board than the previous v6's. It never synced as high as my old ST585v6 and I couldnt even ever get the full Annex M upstream on it for some reason. Also this line normally runs pretty steady with SNRM, but I kept seeing very weird fluctuations which I dont see with any other router.
I heard on the grapevine that Thomson specifically made the v7 on a budget for a certain UK ISP and it uses inferior parts. Thomson is the same company that also pandered to another UK ISP and removed some of the CLI functionality.
Ive raised 4 separate tickets to Thomson and they have never even bothered to respond to a single one.. so right now as far as Im concerned Thomson have gone downhill.
For my own personal line the old ST585v6 works best.. but coming a close 2nd is a
flashed sky router (DG834GT) bought cheap off ebay. On another (longer line) the sky dg834gt works better than the BeBox giveing it a boost of about 1Mbps and running steady.
Theres one router I'd personally like to get my mitts on right now to give it a test and thats one of these
