Wow. I just bought a Diner so i guess I'm a little bias. And I like Dr Dude too.

I also have a WH20 but I've never played FT.

Thats a tough question... so I have to ask a tough question.

What one is the one you really want?

Think about that, and buy that one.

You will never be happy until you do.

Between Diner and DD, I'd go with Diner. DD is okay, but it gets old fast. It's also probably a lot easier to sell a Diner.

How much space do you have? If you can only have one, you should wait for the FT or WH20 that you really want. Otherwise, get the pin you have the money for now, and use it to calm your fever until you save up again for a more expensive dmd. Two pins are always better than one!

We just got a nice FT here locally for 1300$. Not much more expensive than the first 2 you are looking at. It's a great game.

WH2O will set you back a bit.

Between those two? Diner. All the way. It's similar to taxi, except the game is a little easier but the art and theme are TONS better. It's an eclectic game, I look forward to finishing putting mine back together.

I would save up for a WH2O myself.

Wow I feel like you just handed me your wallet and said "Here, spend my money" lol. I haven't played any of these machines so go to the ratings section and see witch pins are rated the highest maybe???

I think it's a toss up but I agree with Gweempose the Diner will likely sell easier.

Here's Chris Bucci's Diner vid, which might sway you!

If you are worried about selling.

2011 book values:

Diner - $1,625
Dr. Dude - $1225

I know these are just "guide" values but it's what I see IRL. Side by side, Diner is a lot better and worth more.

If you have to have one now I would go with Diner. They are both pretty good Pins but Diner seems to be a little more involved and long lasting. Good luck with your decision.

$1200 for a DD seems a bit high unless it's in really good shape. I have seen a couple of them around here go for less than $1000.

Between the two I'd take Diner. Among all the choices, I think saving for a White Water is best. Diner is easy to sell, however, if you need to back out of it at some point to afford the White Water.

I have owned WH20 and FT, played Diner a bunch of times. I have no experience with Dr Dude, but it does seem to be priced a bit high from what I remember seeing them sell for.
My thoughts:

Diner: Fun game. At that price, you should not have much trouble getting your money back. It seems like it would get old after a while, it would be #3 on the list of pins you listed.

WH20: Also a very fun game, however, I personally think it is over-rated. It is commanding much more $$ than the other 3 do. I had one with no topper, played really fast, but it could have used new ramps and boulders...big money investment if that is needed. I just didn't think it was a keeper.

FT: This is one of my favorite games and would be my choice from your list. Lots of neat objectives, great use of what at first appears to be a limited shot selection. Don't hold out for a non-faded cab, just pick one up with the topper and no playfield wear. You can cover any fish insert wear with decals if you need to. There is an easy fix for any reel issues.

Have Fun!

I find the sounds on DD annoying so can't stand it-nuff said

White Water is a classic. Very unique.

You have done good. You could sell that for twice what you paid tomorrow. Hard machine to find.

That does seem like a screaming deal. You did do good. Have fun with it!
