For what you're looking for, I think you may have to increase your budget by around 50%, as L shaped desks are very expensive, with the good ones costing around $300.
You should take a look around walmart or your local office store to see what they have on offer, as Ikea have discontinued the L shaped desk that I use, that I picked up for the AU equivalent of 200 USD. It is a very tough market for corner desks atm, as I remember when there was quite an outrage when Ikea discontinued this desk in the PC community!
Good luck in your search, but here are a few suggestions.
EDIT:
I've found some very good value desks at walmart for under the $100 mark, but the quality is questionable and they do not look very stable especially considering the fact that you are storing expensive electronics on them!
Here they are:
82.98 down from 99.98:

79.99 down from 199.95 (Bargain!):

This is what I mean when I say high quality desks, which is what you are presumably looking for.
$248:

A significant quality and stability increase over the other two clearly, but its up to you whether you want to spend the money.
