Starting with a used set of clubs is definitely a good call. I started golf when I was 12 with a 5 iron, 7 iron and a putter. Overtime I added random makes of clubs, to where I had a full set, but that was stolen when I was around 14. After that my parents got me a complete set of Wilson clubs - cheap $250 set. I played with these for a while, and they actually served me pretty well. I routinely shot bogey golf with those clubs. After a while I started getting the itch to buy something "brand name," as I was always embarrassed of my #%@!!% equipment. I started buying random clubs in used bins at pro shops/golf stores, until I had a complete set of clubs from all different makers..Ping, Callaway, Taylormade, Titleist, Mizuno, Cleveland. The flaw with that is that different makes have different spec for standard length, loft, lie for all of their clubs, so I was doing myself a disservice by playing a random set of clubs. I finally found a cheap set of used irons and went that route, and after that I started posting more consistent and lower scores, eventually shooting scratch golf for the first time in my life on my little executive par 30 course.
You should be fine with any major brand name of clubs. How tall are you? Hopefully you fall into the standard/average height/arm length so that you don't really need to have clubs custom fit and can just play out of the box, but this might have some impact on how you play. It doesn't haven't be complicated if you don't want it to be.
Just be warned - buying golf clubs can become an addiction. It's hard to not want to try new irons, new wedges, new putters, new drivers, new woods, etc. I have made countless trips to golf stores buying clubs, exchanging clubs, testing clubs, etc. It is a long road to find clubs that are absolutely perfect that you never want to let go. Just remember, newer isn't always better!
