Bel has an $80 trade in allowance on the GX65. The trade in can be any brand detector, any condition, so basically the price on the GX65 is $389, which includes free shipping, provided you can scrape up a broken down relic like I did.
I checked around on ebay and about the cheapest price I could find including shipping was around $400 for a new detector, so getting one direct from the maker seemed like much the better deal.
I had considered the 9500ix back when Amazon had them for $414 a couple of weeks ago, but didn't pull the trigger. I figure I'll give the GX65 a chance since I'd rather manually lock out locations rather than have the detector do it. Other factors like the red display vs blue display and the difference between the Bel alerts vs the Escort alerts weren't that important to me.
