any recommendation for rm100-150 range??
ive used deathadder before, suck pretty much. dont like the clean plastic side. have to tape it with masking tape to feel better.

as for Roccat Kone:

im a righty, so wont the extra forward backward button on the right side of the mouse be a nuisance for me??

well if im a righty, then ofcourse im going to use the two button on my left using my thumb. so that leaves the 2 button on the right empty. so i wonder will it be troublesome??(like accidently click on the extra button)

yup. definitely. try playing with a decent gaming mouse for a while. then switch back to a free cheap non gaming mouse you usually get when u buy laptop n stuff. be it ergonomic wise, performance wise, and cosmetic wise.
