2-3K are you kidding me? Are you talking about a full set of leathers and boots? That's totally unnecessary got daily driving. I'm not saying shorts and flip flops are an option either, but let's not go crazy
You won't see me leave the house without leathers, boots, gloves, and of course helmet. On just a short run to the store (~2 miles) I'm in a Tourmaster Intake Air II jacket, Icon overpants, my boots, gloves, and helmet.
KBC actually makes some good quality helmets for the money, I've sold several when I worked at the bike shop and no one had any complaints.
If you're wanting a new helmet the new Icon Alliance helmets are awesome for the money, also the HJC CL16's... I doubt you're wanting to drop the $$ for a Shoei, Arai, or Suomy. I wear an Icon Airframe Carbon Lifeform and LOVE it, but it's still pretty pricey.
I suggest buying a good quality helmet, but saving the exta money over a Shoei or Arai and using it to buy a good jacket, overpants, and gloves. Your skin will thank you.
I can't stress enough also good boots. Atleast over the ankle, I've seen many people get some nasty foot/ankle injury due to tennis shoes coming off in a wreck.
