which is preferable/acceptable

[pescamos]

hi,

which is preferable:

voy a comprarlo para ti
or
voy a comprartelo


lo compro para ti
or
te lo compro

what i'm trying to gauge here is how acceptable is it to say these statements in an almost 'english' way using the word 'para' for our 'for' instead of using indirect object pronouns, so it has the word order as the english 'i'm going to buy it for you' or 'i buy it for you'. I realise that the IDOP 'te' translates in to 'to you/for you', but can you get away without it?

otra vez, gracias por ayudarme,
craig.
