Your other option would be (and this is strictly my opinion), buy a Bergen Intrepid Gas. It's a couple hundred cheaper than the X-Cell Gas, but in my opinion is one of the best designed platforms out there. Every ounce of the heli is expertly designed, made from quality materials, sold with clear instructions, and doesn't require the user to perform the last 10% of the engineering work that the X-Cell does. (You're not the first I've heard speak poorly of the X-Cell.)

Again, this is just my opinion. Take a look at it yourself and see what you think.
