I beleive there is nothing unused that fits your budget. Try going to the field. You will almost surely be donated something. And you can always try the Pay it forward program. Its where people donate stuff they dont need. If you need a radio im sure there is someone who has one waiting for you. As for the tower hobbies trainer, im getting one also. I think the price is great, and hey, your not gonna sit with that trainer your whole life. Im only using mine for about two seasons, and poof taking radio equipment out, putting it into a glider and doing something new.
