There's really only one thing to say about the basic question in the title of the thread: "... buying better quality gear".
Buy it right, or buy it twice.
Examine your budget, examine where you want to be creatively in a few years, and buy gear that will truly serve your needs over the period that you can foresee. Nobody can really see the future, but the site here is littered with stories of folks who "saved a few bucks" getting a short term solution- and then later ended up buying what they really _needed_, and were then stuck with the short term solution (since nobody would buy it, there's not much resale value...). In short, they got to buy it twice.
And I'm one of them. I have gear here that I bought when getting back into this that has no value at all, and had to be replaced with what I _should_ have bought to begin with. Cost me a lot more that way. It's a hard lesson.
Buy the best quality gear that you can afford. Try and widen your focus to take in where you're likely to be in a year, or two years, and buy stuff that will still serve you once you're there.
Get educated, buy the best value you can afford, but never cut corners: it's your art, and you really don't want to spend your precious creative time having to hack around limitations of hardware that seemed like a bargain. Been there, done that, wear the T-shirt to change the oil in my car.
Having said that: Kremitmusic was right. What do you want to do, and what do you need to do it? Focus on where you want to be, not where you are...
