Used all the way. I have had no problems.
My current BCD325P2 was bought used on eBay and at a good deal too. I monitor eBay listings and waited for a P2 to come along where some if not all of the upgrades had already been added for a good deal. Lo and behold one showed up on eBay for around $350 and I scarfed it up. You can't even touch a new P2 on Chinazon for that price not withstanding the needed upgrades of DMR, NXDN and Provoice. Well, I have no use for Provoice, but the other two I do.
On the other hand, I did buy my 996P2 new on eBay out of Canada, but it too was a good deal compared to Chinazon.
Lets just say I have a very novel way of searching eBay and also getting an alert within 10 or so seconds if the item I'm looking for is listed . I also use Gixen for snipping. Not only is getting a great radio nice, but getting it even cheaper is nicer yet and to me that's the name of the game. It's like playing the stock market so to speak...
Heck, I shop at yard sales all the time too. The greatest deal of my entire life was from a yard sale. For a while I wanted a CH Products yoke and pedals for Flight Simulator. At the time, the yoke and the pedals sold for about $300 EACH on eBay. Then one day I was at a yard sale and there they were, glistening in the Sun like
Manna from Heaven. Cautiously I asked the guy sitting next to his wife how much he wanted for the yoke and pedals as I figured he probably wanted a pretty penny for them. When he said, "I'll take $25 for both" I had two immediate thoughts fire through my ≈200 MPH neurons: 1) "holy crap!" and 2) "I bet there's something wrong with them." I figured if there was anything wrong with them I could fix it so I handed the guy a Jefferson and went on my way. With high hopes I plugged the yoke and pedals into the computer and looked in the devices of Windows control panel to see if they would show up. Sure enough they did and each and every single button and lever functioned as well. And to my amazement FSX (Flight Simulator) automatically assigned most buttons for me, too. LOL! Now THAT is what you call a good deal on something used.
I bought my AOR AR8000 on eBay for a decent price of $100.
One thing I notice with eBay or Goodwill's website is that Ham gear goes for waaaay too much and there is waaaay too much competition. That I find to be ridiculous. I just shake my head every time I see some 20 year old radio go for good money.
Moral of the story: buying used is a no brainier in this economy and all good things come to those that wait.
