Heh. I'm going to be no help at all, because I'm going to suggest a method that actually involves
more work for the DM
But one of the most interesting high-level character generations I've been involved with was for a group of 10th level characters. We submitted a 'wish list' to the DM of the magic items we'd like, of approximately the expense dictated by Wealth guidelines (though it wasn't important to be exact), with some rankings of how vital we considered them.
The DM took the lists away, and returned slightly different lists.
Some items were gone. For example, I didn't get my Bracers of Archery
Some items were different - the +1 Battleaxe I requested came back a +1 Spell-Storing Battleaxe.
Some items were the sort of thing a character might have picked up over the years, but woud probably never put on a shopping list - like Boots of the Winterlands.
And there were a couple of interesting touches we wouldn't have thought of - like an everfull quiver of masterwork arrows.
Getting the list back was a little like opening presents at Christmas... you'd dropped hints to your parents that you really wanted an Optimus Prime, so you were pretty sure that would be in your stocking... but you didn't really know what else might turn up...
It was great
