drof, the SMC7004BR is the SMC Barricade router... it's a good deal in it's own right... it's got more features and better specs than the Linksys (in about the same price range... use buy.com and coupons, etc...) plus a $20 rebate (good until the end of october).
The question is about the D-Link di-704 though... this router will be quite a bit cheaper, but AFAIK no one has reviewed it yet.
Another hot deal is the Addtron adr-e200p, with similar features and sells for less than $80!!! (but again, no reviews yet)
