Bill - nope, it's the DI-614+ (the 624 is 802.11G - mine's 802.11b - notice that they're calling them "Airplus Xtreme"...copycats...)
http://www.dlink.com/products/?pid=20I got mine at on the day after Thanksgiving...I was one of those loonies lined up to pay at 7:00 AM (the darn line for the cash registers went right around the perimeter of the store...) - $59 after rebates, if I remember correctly. Best Buy don't list them right now on their web site, but you can find similar prices on PriceWatch.com, and even better...just found this at Amazon:
DI-614+ for $45 - free shipping too!
It's a good router - has much better range than my snow Airport base station, which is STILL sitting in the box under my desk awaiting an eBay auction. One of those things on the to-do list for this summer that just isn't going to happen, since I'm off to Newcastle, ON for the usual 3+ week "invade the grandparents cottage" routine at the end of the week. This summer has just flown by - as usual.
