I just noticed that the Tecsun PL-880 is available to purchase as a pre-order from Amazon.com.
The vendor (Electronnix) claims that the PL-880 will be “released” on November 30, 2013.
The price is set at $149.00 US; at least $20 more than the Pl-660, depending on the retailer.
Though the PL-880 is available for pre-order on Amazon, I’ll most likely hold out an buy from my favorite eBay seller Anon-Co in Hong Kong. I’ve bought numerous radios from them in the past; their pricing and customer service are hard to beat.
I will review the PL-880 as soon as it’s available.
