Far better imho to sign up to one of the e.g. 50pcm (for 12 month) deals that give you a 25% discount in the solo rate. Are there any flying clubs in your locaility that do this? Let the club do all the admin for you, you will appreciate it. You have access to potentially more aircraft anytime, which is weather variable, fly it as little, often or as much as you want (within clubs rules) only having to pay for the time you fly.
