The question comes down to uptime needed. If this needs guaranteed connectivity, a (true) T1 offers this. Most cable connections don't have the same uptime guarantee. I agree that the likelyhood of 500 hits to a text rich site us unlikely to saturate either. But at the same time, 500 hits tells me that it might be even better to just let someone else host the site since you'll get better uptime guarantees than you'll likely be able to offer yourself.
