First you need to figure out what motherboard you have/if you need the SD reader. The TX tutorial will be really helpful for that. Honestly, that guide is going to be your biggest help. You will need both a glitch chip and a reader. There's no way around that.
As for glitch chip: there are a ton. Matrix, TX, Squirt, and several others. If you want the easiest choice, just follow the TX tutorial list. Otherwise, you can go about comparing prices.
