i cannot afford expensive items like manamana etc, is karacha crossbow+arde dagger better that khasti bow??
wow, karacha crossbow is already expensive as manamana recipe, prices are the same in telsias server, just buy manamana recipe and farm the materials, quite easy for a fletcher to kill honeymeli stinger 
but always keep khasti bow and xbow + offhand to switch between flying mobs
in my server (Varena) karacha xbow is 2m and manamana is 6m+, my god wish im in telsiai xD
Keep in mind you always will be switching between Bow and x-Bow depending if its flying-type(bow) or ground-type(x-Bow).
Awesome Itens .: Catacombs Shooter + Manamana
Maga Bow
Medium Itens .: Grajus or KarachaX-Bow + Arde or karachaDagger (Do not use karacha combo).
Khasti Bow
Cheap Itens .: Spiked Crossbow or Black Tip Bow + Arde.
Lethena Bow or Rogue Bow.
I strongly recommend you to not spend much money on 170 gears, just get the cheapest item available and when you reach 220 then you get some kickass gears.
Note: I did this list based on itens on SILUTE server.
