Nothing wrong with the cheaper Tasco for now, what matter is you need to go out and shoot!
When you have the $$ then go upgrade to a nice one. You will most likely end up keeping the Tasco anyway. It will always come in handy as a backup scope. I have about 4 optics right now since I never sell any of my previous cheap ones.
If you don't like it, then you can always return. So try it out and have fun.
