For less than 3,000 you can buy enough stuff to get up to a x3 multiplier. Not to mention just from running around fighting stuff I usually have a backpack full of random biological parts that I can stuff into an item for XP bonuses.

It is actually better to use items with low experience to raise the multiplier. Every time you level up an item the amount of XP an upgrade material will give decreases. So if it goes up a few levels when you are maxing out your exp multiplier you could be looking at 10% less exp from the main component dump.
