by the looks of your posts...youre on a pretty small budget.
just a word of advice: yea you can find good deals...but generally in the mtb industry, you get what for you pay for.
RST's price may be very attractive, but with the amount of bad reviews out there, its not even worth looking...yet at least. you can find a used Boxxer or 888 that will work 10x better than a new RST, for the same price.
