i owned a ibanez 270 and 370Dx,
personally, i think the quality of the guitar is great, and i also tried the LTD model u mention in Mid-valley 3rd floor....
well, i think 370DX is far better in terms of neck, design, pickups and the bridge compare to LTD, and the basswood give u better sustain.

i not sure about the price in Malaysia, but my ibanex was bought in US last year at the price of USD 285 (about 1083 ringgit) after a discount and price beat.

the later INF pickups give us a heavier tone compare to the ibanez standard pickups used in 270DX.
this is all i can tell u~
