maybe some more info...what type of application or what is it going to be used for? daily driver? drag car? toilet racer?

how much power do you want? what are your concerns?

I was told once...you have 3 options: fast, cheap, reliable...

you can only pick 2. If you want fast and reliable, it won't be cheap...if you want fast and cheap, it wont be reliable...if you want reliable and cheap, chances are it wont be fast at all...
