Hi Troy,
Yep I flew them and crashed them and really had a lot of fun with them.
The twin rotor coaxial are definately a lot easier to fly and cheaper to buy until you get to the larger size and then they become a similar price to some of the single rotor full collective pitch machines.
The single rotor machines have a very steep learning curve to come to grips with but there a some great flight simulators that let you gain a lot of stick time before you throw your money at the ground.
I always told the wifey that the ground came up and smacked it really hard
But seriously they are a lot of fun I haven't priced them for a while but the single rotor machine in what is refered to as a 400 or 450 size is fully aerobatic and a kit from a local hobby shop ready to fly with radio gear and batteries, the works $500 for a good one that you can get parts for after any small misshaps.
You would have to check current prices but the Brand names are Blade 450 or TREX 450. there are others but your local hobby shop would have to let you know what brands they deal with.
Another option is the quad copters do a search for them to have a look they are a lot of fun and cheaper and easier to fly, I,ve flown one of them and they're much more crash freindly than the others and easy to fly be a good starting point.
Here is some crap video on an even crappier day of my 600 size TREX Electric ( electric is the way to go )
But have a look around youtube at the ones I mentioned above and also for quad coptersand coaxials, give you a good idea of what they can do and then it's just a matter of how many dollars are involved.
Hope this helps.
