You may be able to find one easier for Docsis 2.0, but I only know of a few Netgears and even some SMC brands that do both modem/router combos offhand.
Docsis 3.0 is very limited at this time. The only supported models are the Cisco DPC3000 and the Cisco DPC3825. The 3825 model is the wireless version of the 2, but I have not seen many of them purchasable yet. I have seen a few in online markets sites, but nothing I would feel secure buying through yet.
