Hey Guys!
New user checking in.  I've been active on /r/cade and have been watching John's videos for a few years(!) now.  
I'm a private collector with 13 machines!  I've always been in the arcade scene.  I grew up very close to an arcade that I frequented very often.  Later in life I ran an Aladdins Castle arcade for many years.  I have an extremely supportive wife that also enjoys playing some games with me now and again.  We have two girls, ages 2 and 4, who also enjoy spending time in my arcade and playing some games.
My very first game I acquired 5 years ago is a dedicated Mortal Kombat.  I bought it off of eBay for a ridiculously low price.  It basically opened my eyes that this hobby is possible.  I can own these myself!  I know how to service them, I can do this!  Since then I've been buying and trading and upgrading, and loving (mostly) every minute of it.
Here's my list:
Mortal Kombat (Dedicated, also has MK2 boards I installed)
Soul Edge (converted Midway cabinet)
Hydro Thunder (Dedicated sit down)
Dance Dance Revolution (Currently running Extreme)
60 in 1 (I'm out of room, it's my compromise to have more games)
Gauntlet Legends (Dedicated cabinet, bought this for my wife!)
Neo Geo (Dedicated 4 slot)
After Burner (Dedicated Upright, even has working rumble!)
Silent Scope 2 (Dedicated)
Dance Maniax 2nd Mix J-Append (the best version, hard to find)
Revolution X (Dedicated 2 player)
100 CD Jukebox Rowe Laserstar
Skee Ball (no logics, amazingly still fun)
I loaded my jukebox with 80's rock and hooked up surround speakers around the arcade.  I have rope lighting and a red beacon spinning for ambiance.  
I'm really looking forward to being part of this community!
Welcome to the site! Lots of great people here. Thanks for watching!
