As I said earlier, I was disappointed with the speed of my Vigor 130, albeit a very crappy unscientific test on my part. That was on sub-2Mbps d/s ADSL1 so be warned about the relevance. Loved the zero-config fesign of it, brilliant. It just works. The possibly-unique protocol conversion of PPPoE on the Lan to PPPoA over DSL is a killer feature, extra speed literally for free (relevance depends on your chosen MTU), and I love the full MTU of 1508. So I absolutely love it, just wish it happened to be more aggressive in my case.
Would always want to give one a try because at 1508 MTU it just beats all other separate modems if at the same DSL bitrate (i.e. all things being equal) by 3% for flat-out downloads because of the greater efficiency of PPPoA. (In fact, the speed efficiency gain depends on packet size, see my wikipedia piece on PPPoEoA efficiency, difference will be zero for 1492-byte IP PDUs, or huge, v roughy ~+100%, for very small packets.)
