from what ive seen the STPL's are on the rise and are valued just about the same lately.... Might be a stretch to get either BNIB for that price, but you may find a used pair in that range without too much a problem if one were to pop up that is
its more than just abit, i know people in the states pay about usd400 odd, here in Singapore the cheapest is around SGD600 plus. and its almost impossible to find in Singapore at that price.
