I have a Panasonic RQ-S55V in mint condition and an RQ-SA79 in mint condition with all accessories (charger, 3x original batteries that play for 3 hours each, power supply, AA battery adapter).

How much are these worth each now?

Ignore James, he's our resident antagonist.

Welcome and yes, this is the correct place to post a request like this.  We do have a 'What's my XYZ worth?' thread but it isn't working as well as I'd like. 

It's very difficult to give valuations as it really depends if anyone wants them at the time of asking.  My advice to you would be to look at completed auctions on eBay for similar items, failing that, just list them on ebay and see how well they do. 

Though, if I was honest, these aren't really very desirable items and I'd be surprised if they fetch $20 each.
