eriepamarty: I was wondering should my next purchase be a new driver or a new set of Irons.
Which will improve my game more
On a small budget: Don't buy anything, because anything will promote you to Master and to the need of even better equipment, pling-pling.
If you insist, start with a 3WD, replacing the driver at low cost. Next, two short(!) wedges, maybe the L39 ATV + one Gorge, or 2x ATV (L39).
You may start to use custom balls like the B-ES.
