My experience a couple of years back was similar. I started with a Superstar 60, and had problems getting instructor time. I ended up buying a GWS Tiger Moth and flying at the local park for a while then went back to the field with a 3 channel Ripmax Zephyr which I flew myself despite not being certified solo. Later, I went back to the Superstar, and finally soloed on an LT-40.
Be patient, it can take a lot longer than some people would have you believe.....
