If you have limited cash go for gliding, but you will need time, several gliding clubs do weekly courses and I'm sure that 3 weeks training would get most students flying solo but don't do them together spread them over a couple of months. Wait until good weather maybe April before booking courses then you have a chance of flying most days, remember gliding clubs don't expect you to just turn up and fly, you are expected to help out with ground duties and maintenence. It is not like power flying where you turn up pay your cash and go home, one weekend day a month is the commitment you might be expected to do, maybe you will have time to fly, maybe not.
