Don't waste too much zeny on Hunter/Sniper gear, save it for Ranger stuff like White Wing Set.
And try to focus on Arrow Storm for Ranger, that's by far the best you can do to level.
That said:
Hunting Bow + Hunting Arrows + converters are cheap and awesome.
+7 Octopus Hat is super awesome for making Fresh Fish heals really good - you can farm Certs yourself if you're tight on zeny. Rideword Hat/Vanargand Helm are also great, but kill your budget.
Early Ranger must-haves:
White Wing Suit (upgraded as high as you can afford)
White Wing Manteau
White Wing Boots
1x White Wing Brooch
Elven Bow + Elven Arrows are better than the Hunter Bow combo, but Hunter Bow + Hunting Arrows still work for quite a while even as Ranger (remember to use Converters/Endow for elemental advantage)
Other neat stuff:
Incubus Pet - helps with the SP upkeep, especially if you don't have a Rideword Hat or Vanargand Helm, you need to remember to feed it though or it will run away
