So I have the ability to get one NIB pin, and will probably be my only one for a long long time (if ever). I have narrowed my choices to TNA or AC/DC Vault Premium.

What I need are some opinions from TNA owners/players that have been around the machine a long time. The reason is because I have a small collection of two EMs both of which seems like they may play similar to TNA. I can't get over the feeling that with TNA, I would have 3 similar machines. I have played TNA a few times, but not long enough to get a feeling if I would get bored. Where as, everyone talks about AC/DCs deep rule set.

My collection:
Argosy - Has a spinner and upper area with a sling. Most action is on the lower half of the play-field.
4MBC - Has physical ball lock, with the ability to steal multi-ball from your opponent.

Here is how I see it

TNA
1) Great Theme (art, sound, etc)
2) Fast Addicting Gameplay, just one more game!
3) Straightforward rule set - may get repetitive after owning for a long time?
4) Co-Op mode

AC/DC
1) Big Fan of the Music
2) Lots of different shots
3) Lots of different modes
4) Seemingly vastly different than my current machines

I would happily have either machine, but with my current collection I feel like I need to go AC/DC.

Convince me!

Waited a few days to see the responses to me thread. Glad to see it sparked a bit more debate than I was expecting. But looks like the choice is clear. AC/DC

Now to find one (non-luci), or a distributor with with one left sitting around.

Thanks everyone for chiming in.
