I simply started this year with a Boomerang Nano. It was a second hand buy, and saved loads of money. My advice to you it to buy your first jet secondhand. The most important question you should ask about any airframe is how easy is it to land? They are all annoying to land at first due to residual thrust, and throttle lag, but you get used to it! Also some will need longer runways than others, so I guess it depends on your club?
