I guess this hobby is pretty much a learning experience and thats fair enough, also I take it the metal up-grades are deffinetly worth it, so those will go on the list as well. I guess I'll just run the hell out of my tank, when it breaks I'll do as FreakyDude said, I'll just pull out the tools and fix/replace the parts. And FreakDude thanks for the offer of help, I just might take you up on that from time to time .
Thanks All,
Paul
