Anyway, I just want to see as well, does anyone think using cheaper clubs will give me any bad habits? say if I was to upgrade them, would the fact they might be "heavier" or something make a big difference, or is that the same as going from say a set of Pings to a set of Callaway irons?
No, a good golf swing will result in a good golf shot, regardless of the club in your hand. The clubs you bought will be fine to learn with. As you come to enjoy the game more, you will start to appreciate the differences in the clubs, and then you yourself will be able to start to form an opinion of which clubs are right for you.
At this point in time, enjoy the game. Don't worry that the clubs you bought didn't cost alot. Also, never judge a golfer by his clubs. I once had a guy show up with a nasty old leather bag filled with mismatched clubs including some Spaulding Executives from the mid 80's, a permission driver, a Taylor made burner bubble fairway wood and a cheap putter.
After shooting 3 pars in the first 4 holes, I got to talking to the guy, he was an experienced golfer that was traveling on business for several weeks and when he discovered what the local courses wanted for rentals he want to the 2nd hand store and picked up that bag. He even said that one of the clubs in the bag he was probably going to ship home because he holed out a shot for eagle with it a round or 2 prior.
