A possibly cheaper option would be to get an unlocked cable modem that is compatible with their service.
In my area anyways, I can go to my TWC "PayXPress" portal (e.g: your online billing control panel) and on their support page they list links for compatible hardware.
Another suggestion: instead of bridge mode, look for an option called "RG Passthrough" or "Gateway Passthrough" or even just "RG enable"... then get your own router and wire the router's WAN port to the 1st ethernet port on your cable modem.
My motorola surfboard SBG-6850 has this option; and it works while bridge mode fails. I only use it because they want $5/mo to enable wireless on my cable modem. That's right, they want $5/mo to enable some hardware I already have.
I remember a time when MODEMs were just that and nothing else. I would be miserable if my ISP forced a router and wireless access point on me. Cheap routers that have to be reset once a week shouldn't be forced on anyone.
My $50 Linksys WRT54GL goes years between resets and then it is only because I am moving.
