Dilema - Need Help

[Nemain]

Ok picking up the new tank tommorow. It is pre drilled, unlike the cursed one I have now, but thats an improvement I am happy for.

My problem is: LFS says that I need a new filter ( a trickle filter, not canister) and pump, and pluming, lalala etc.

How much of this can I get away with NOT buying for the interum? I was planning on switching my fish over to the *ecosystem* at the end of the month ....

Any help would be great! Thank you all muchly, and BTW - AG tanks were wonderful about the entire thing =) Very profesional.
