sure if u dont mind loosing a few hair on the 1st one after that its extrmely ez, depends which area ur (pure ntl/tw) a motorola 41/4200i can be quite ez if it doesnt have lock firmware all u would need is ethernet cable and away u go but a 250 is way cheaper
surfboard 4200 or 4200e depending on area cost more but much easier, but on ntl modems 250 easy the 200s are tempramental to say least had 2 just die 4 no reason but 250's are better both looks and performance
4100i, 4200i, 4100e or 4200e, if you live in TW or Pure N*L.
If you ive in EXCW, the 4100e or 4200e
With the 4XXX model Moto's you normaly wont even need to open them just connect your ethernet lead, providing you don't get one with locked firmware. If you are unlucky enough to buy a locked model then you will need to use either a Max232/233 or a Blackcat cable.
