I have one.
Trouble?
Well...the only significant trouble happened starting last spring near the end of the riding season here in AZ. The machine felt like it would lose fire, but would start right back up. This happened 2 times in 2 rides. Then, finally, it stalled and gave a "Christmas tree" on the dash 3 times In about a mile on ride #4 after the initial issue. Then cleared up again and ran fine. The good news with that, is that it gave some direction to go, where as the first 2 were so isolated and quick there really wasn't much info. I replaced the ignition switch, and all has been good for 4 rides now, so I think I got it.
There was a recall for the steering knuckle/bolt that I did myself, but that's just one of those things that happens with a mass produced vehicle.
The one thing with 700's....it's so hit or miss I'm hesitant to mention it...but they have been known to eat a cam. Seems like short trip machines suffer more from this, so give the thing a long ride when you can.
Less serious 700 issues:
Door rattles
Bed rattles
Exhaust squeak at pipe joint.
Rear diff is noisy as hell.
Requires warm up in cold before it will shift normally.
Can get thin on power at high elevations.
The camo will eventually peel
Others will add more...
This is my 2nd 700, the 1st being a 700-4 that I sold with just under 9000 miles with one $2 seal as the only issue. My current one seems to have taken a step back in build quality, and I wonder if it's going to give the same service as that 1st one.
Accessories:
Badlands winch w/kfi mount
Honda soft top
Cheap ass rear view mirror
Rear sunshade
Lots of heat shielding/sound deadening
I'm not big on throwing every accessory I can find at things, as you can see.
I specifically chose the 2 seater this time around. It's cheaper, lighter, and the lack of a rear roof helps sound. The 700 isn't the loudest sxs, but it's by no means quiet. I also think it looks better.
Certainly, if you can get a ride in one, that would be ideal...
Would I buy a 3rd?
Honestly...I dunno. Machines like the Wolverine X2 or Hondas own 1000 are serious competitors. The 700 has moments where it's so special that its a shame some of its shortcomings can spoil the party. I guess it depends on when you ask me, but I do wonder what life is like on the other side.
