Wind
I've just recently solo'd myself. My 2nd time out by myself was Thanksgiving day. I really wanted to fly but there were 5 other guys at my field just sitting out the wind. I said "what the heck!" and I took up my .40 size trainer. I had a great time! The wind made flying a little different but it was fun. I admit that I had a rough landing. I bounced hard on the runway then landed in the grass. I bent my nose wheel back about an inch. No big deal, I've done it before, it just needed to be bent back out. After my flight I saw one other guy get his plane in the air. I guess he thought that if a novice like me could do it then he could.
One thing about having the inexpensive trainer is that it takes some of the 'Pucker Factor' out of flying. I have to agree that it also has a lot to do with comfort level. I've flown in heavy wind with my RealFlight G2 sim and I kinda knew what to expect.
What ever you decide, have fun and stay safe.
