I think that ultralights offer a great way of getting into the air without having to pay up to double the price for other light aircraft. I would certainly consider learning to fly ultralights before other GA aircraft, because there is quite a big chance that I might actually like flying these small sport aircraft, and not have to fork out as much as compared to flying, but still get the frill of flying, and gain a licence. For me their are heaps of benefits such as the aircraft being smaller hence cheaper on fuel. Cheaper to maintain license, cheaper tuition to obtain license and also a possibility of actually owning a small ultralight.
Ok it's not everyone's preferred route or option, but it certainly appears attractive to me...
I also have an ultralight centre 8 miles from me which makes flying more viable for me.
