Save or Splurge

Should I splurge:

The Prada Double zipped Saffiano Tote for circa $2k. Calf Leather and super luxe, so gorgeously classic, it'd be safe to assume this'll last you through your lifetime. But there's a massive waitlist in David Jones they tell me and I might not have a chance with the popular colours before the next price increase. *Gulps*

Or save with:

DKNY's Saffiano work shopper tote for $420 from David Jones? It looks the same, functions the same, but it is lighter in weight (not to mention easier on the wallet). It is available rightaway.

But it is DKNY versus Prada! Is there even any comparison to be made?

If you don't get it, then you are playing for Team Mr.HEA, but in his absence, I'd love to hear your thoughts to help keep me grounded. Or enable me...

Patience isn't quite my strongest virtue though I warn you, I might end up going nuts trying my best to not cave in.
