True, with this kind of price where now the rental needs to cater mostly for highly paid expats or the rich for own stay, a unit in KL city with the same price is a wiser choice. Having MRT/LRT does not necessarily means the place is posh it's just ease of convenience, KL city to many professional expats is still 'posher' than most Klang Valley areas.
Looking for flip is worst IMO as this pricing is too risky to gamble on capital appreciation...
