Two ways to look at this imho
1) buy starter gear, all well known ( aka the stuff in the mags at the moment ), maybe used if quality is certain, and enjoy...knowing resale wont be a long process and upgrades are coming someday.
2) do a lot of research, more listening ( travel if need be ), decide what your top budget is and what you prefer, and then add 20% to the budget and go for a long term system :)
In any case do it! Spinning records is great fun.
