Those cabs are dirt cheap and you cant swing a dead cat without hitting one.. There's about a dozen on eBay at any given time.
I have a Bad Dudes (same cab) in great shape I picked up for 75 bucks a couple years ago at a skate shop. I've always planned on reskinning it as a robocop. The curved marquee's really make those cabs unique. I also have a 25" data east cab (Cobra Command atm, soon to be my big bad figher cabinet). They're really cool cabinets, easy to work on and in, and easy to convert.
Not that I'm dissin your skills, good job on the cabinet. Just seems like a whole lot of work for something you could have bought for probably a fraction of what you paid. (Yeah, I know thats not the point).
As a side note, where'd you get the monitor bezel and side art? Are they original or repros, and how much did they set you back? My cabinet is missing both.
