Well, not for $5, but I have these 2 clip on lights that I really like:
Might Bright TravelFlex - takes only 1 battery so it's not that heavy or costly through battery consumption.
Verso Arc Light - pricier, but it can be used on most any reader, and I love that it's rechargable, saving me on any battery usage. It has the same plugin as my 350, so easy to recharge, so it's my favorite between the 2, especially if I'm out of the house.
But either would be much cheaper than $140.
