I think it is only a good trade if like the games that you are trading for.
Blitz is pretty fun with a good replay value
same with golden tee and I don't know about rev x
As far as a value stand point you would be coming out ahead assuming that they are all dedicated cabinets in good condition.
I think thats a good trade for you, isn't rev X a giant heavy cab? If you end up wanting to get rid of that GT 2004 let me know. I was trying to work out a trade with him also but I don't think it's gonna work.
I vote good trade, but it would hinge on the condition of the MS PAC. If the condition is average, I'd go for it. If the condition is great, awesome, expceptional, etc. NO WAY.
