The best way I know to become tuner-literate is to get an Elderly Instruments catalogue. They've got just about everything on the market listed, and if you're a music nurd like myself, you'll find hours of happy reading. Some personal opinions: Grovers and Klusons are the veterans of tuning peg history. Shallers are modern and well-thought of, Gotoh-Gut are cheaper but work fine. Stay away from Grover Imperials- they look great but are VERY inaccurate.
The ones you describe Murray are probably budget Korean tuners (which doesn't mean they're bad). If you really want to spend that money from your new raise, you can get custom tuners for about 500 bucks. Only you (and maybe me) will know what they are, but it's cheaper than a Rolls.clank here
