For now, if you can afford the $50, I would purchase a DOCSIS 2.0  
cable modem.  DOCSIS is a standard (a laughable one, but I digress),  
and a DOCSIS cable modem should work with 99.99% of cable operators  
out there (at least in the USA).  I'm surprised that DOCSIS 1.1 has  
been obsoleted in some places, but as those old Cisco UBRs die and get  

DOCSIS 2.0 is not likely to be obsoleted soon, as the DOCSIS 3.0  
specification, as far as I know, is far from complete.  Once it is  
ratified, and cable operators start using DOCSIS 3.0 headend  
equipment, then you'll likely have to buy a new cable modem.  (One of  
the main features of DOCSIS 3.0 is channel bonding, which allows the  
modem to see more than 6MHz of channel spectrum - the hardware in  
DOCSIS 2.0 modems will not allow for this.)
