sir, in my opinion, both cars are durable and reliable.
if your carrying eggs, well, go with strada for softer more carlike ride. but if you are carrying something heavier, ranger has higher torque.
if you will buy at the end of the year, most likely they will give you discount because it will be 07 instead of 08.
now with the price difference you mentioned, its not bad because you have ABS,EBD,LSD that GLX doesnt offer. on the other note, bedcovers are less than P10K, stepboard are around that price as well.
you can probably haggle for free LTO, etc for both unit.
again sir, both your choices are good.
read the strada and ranger thread, you will get the owner's feedback on their trucks. also...drive them both.
