Same here: I,too, thought the cheap stuff is good enough for learning and I get to proper supplies later. Worked my way through all kinds of art media to find out what I like, and any supplies I could get my hands on...
Although I did find the odd bargain in the lower price segment that was useable and enjoyable, on the whole I ended up with the well known brands. There is a reason professionals buy them, and many reasons why they are more pricey. Lesson learned.
Oh well, as long as it's fun...
