Initially, I'm thinking it wil be the standard RadioShack full price of $499.99. Once the dust settles, then you'll see some sales.
I do recall that the Pro-106 was introduced at $299, while the Pro-96 was closed out at $199 during the same sale. (I opted for the Pro-96, which I went on to regret, given my fringe LAPD location.) We are seeing discounts continue on the Pro-106, which we assume isn't being closed out, and expect that RS will still include advanced-level scanners in their lineup. Still, the continued price cuts seem to me to represent a new paradigm for pricing, unless they actually were trying to get rid of them.
I don't think we'll see another $299 intro, but they've set the environment up pretty well for a $399 price. I think that $399 will be RS's street price for the Pro-18, with frequent $379 and $349 sales, and some holiday opportunities of $299. That way, they can float the Pro-106/197 price back up a little, inasmuch as it's an "advanced scanner." They need to keep the price near the top end at such time as the 106/107 replacement comes out.
Meanwhile, I think the value-added Pro-800 will street for $449 to $479, and $499 from folks who tend to always sell at full retail.
RS employees admittedly have a hard time supporting the advanced scanners; I think the Pro-18 will be welcomed by both the customers and the salespersons. I think they are correctly betting on the Pro-18 being a big seller.
