When I was looking for my archtop I tried the 300, 600 and 700, side by side. In my opinion the 600 was definitely superior to the 300, but the 700 was pretty much the same at the 600 (at least on the ones I tried). I decided that a LH600 would work fine for me but then a used 700 came up for a really good price and got that one. I would definitely go the 600 over the 300 if I could, but wouldn't fork out the extra bucks for a 700 (unless, like me and mawmow, you get lucky). Like mawmow I also had to do a bit of my own tweaking to get it to play how I liked.
