Also, when you do get some air tools, don't forget the air tool oil( I like PB blaster brand). Oil your tools and run them once a week(min) or at each use. I do industrial maint for a living so trust me, this is a must to keep your air tool in good shape. I have a C & H die grinder that I have had for 10 years and it is still going strong. A die grinder is a cheap must have!!!!! Also, drain your tank pretty often to get the moisture out so it wont rust.
RIO: LOL, yea there's a big learning curve when "driving" it. It's way overpowered.
Believe it or not i've lightly ported and polished the cylinder and added a K&N air filter to it too. The weird thing is that the porting and polishing didn't make it much faster because now all it does is spin the wheels like mad!
RC: Try looking at harbor freight tools. Sometimes you can get a crap load of connectors from them for next to nothing. Same goes for ebay.
Yea he's right Harbour Freight is where I got all my connectors. They were like 20 cents each. I bought a bag full just in case. I also bought my Ingersol Rand 90 Degree die grinder with to sizes and 8 grinding stones for $49. Harbour Freight stuff is cheap so becareful what you buy. I did buy there pneumatic cut off tool for $10 though and it works good (25,000 rpm) for what I paid for it.
