Again, I go to post a little something see a bunch of people already doing just that....:-)  But in any case...  Here are my specs.
I am a 3D Computer Grafx Designer for over 18 years.  Working as a 3D Modeler for an Arch/Eng company at the moment....
See this link.   
www.dbfinc.com/studio3d/pdf/s3dbooklet.pdfGot into Mame a LONG time ago and then not....  But REALLY into it now.  Here are a couple of examples of MY cabs
MameGear...  The Theory of Arcade Chaos...  A play on words from my two favorite games... Splinter Cell and Metal Gear... SNAAKE will agree.  :-)


Now, that was my first one and since I have made tweaks, but gotta take some new pics...
Here is my Driving Cab
Speed Racer

And finally my Pinball Cab
Spaceballs  It was Pin Wars... but I like this better... both sides show...  The helmet on Darth was a joke... 


My rates are comparable to most, but it all comes down to what you need.  I will tell you, that I am sort of anal and a perfectionist...  So most of time, I spend more time than I should. lol
Also...  This is not really to complete with anyone as everyone has their own taste/talent/expertise etc.  So if any of you other guys get swamped and need help getting a deadline done...Scanning, linework, coloring or whatever...  I would happy to help...  I have some extra time.  
You guys can email me at  eric@basementarcadegrafx.com  
So thanx for checking this out and if anyone needs anything at all, just give me a shout.
Thanx
Eric
