tzechuan,
well, i have a pioneer player in my moms house, and i like the pioneer better. in order of preference its pioneer tops, philips, and finally enzer. i havent calibrated my tv at all, its just been adjusting the colour to what i think is the best.
for me the enzer is the work horse player, may not be pretty, may not perform extremely well, but performs when the going gets tough (kids using it).
I wanted to add that if ever the Enzer fails, I just buy a new one. When the Philips broke, it cost me SGD350 to fix it... I could have bought 3 Enzers!!!!
