I assume you are talking $320? That is a good option. My experiences with A4L have been nothing short of stellar! I have read rare accounts of people getting a defective unit, but that is on the manufacturer. A4L has always taken care of those instances in a fair and professional manner.
I have bought over a dozen items from them and most could have easily passed as new, the ones that did not were not anything that you would notice from over 3 feet away (for example, something like a shiny rub spot where one of the feet from another unit had sat on top of it). I have no problem with that type of blemish because it is the kind of thing I am liable to do with my own gear. Fortunately, I have never received (or read about someone else getting) an item with significant damage (like, say a unit that had been dropped on one of the rear corners). All functioned perfectly and I consider the savings from buying through A4L as free money!
