What is the best way for me to buy the games I review?

I have been debating this for a long time now, because buying and reviewing games is great fun, but also very expensive. I know a lot of other review websites out there make contact with the publishing companies and ask for review copies of games, which is one option. But I think that I would feel that I was somehow “indebted” to these companies in some way to give a good review if the company was really nice to me.

The other option is to put a “Donations” button on Mini Game Reviews, and then use this money to help buy some of the games for review.

What do you think? Do you have another suggestion? I would appreciate some feedback on this.

Thanks in advance.
