Premium Item Recommendation?

next thing on my personal list is Frink's lab. (Put serious consideration into buying him after the donut-fest that was Halloween, but I got the ray gun instead.)
Why? Well, he's entertaining. Every time I see him in a neighboring town he's doing something cool. More than a lot of premium characters, he gets to be part of the storyline (Halloween walkthrough talked about him having a goo task, though a lot of premium characters didn't, not even Boobarella) and the building is pretty sweet looking. Also, it's one of the higher-paying buildings on the premium list, hourly.
I've seen a few people express regret over getting the open-air stage, but with the new multi-tap system, they probably aren't regretting it as much.

I would wait for Christmas. All of your items will be available until Christmas which may only be a 2 week wait (maybe 3)

If you are looking at the best value bonus % boost, it is 20 donuts for 1% bonus.... white picket fence, police cars, burns limo, mini nukes all offer this level.

so, a couple of police cars and 10 picket fences gives you 4.5% boost for only 85 donuts :D

I'd g for Frink's lab. Frink himself is a great voiced character and he has some really good outdoor tasks.

Plus, if you have the Ultrahouse 2 and the ghost zapper, you can add Frink's lab to them and make a cool futuristic area, like this -

I'm in the same boat. I was considering the school bus with Otto but I got 30 donuts in my last box and now I'm at 154, giving me more options. Frink's lab is cool, but I'm leaning towards Krustilu Studios, simply because I would like to build an entertainment lot next to my sports complex. Boy, this conversation would sound ridiculous in real life :-)

Lab... Why? Well the rest don't have much animation and the open stage it's like channel nine only if you want to use it for 24 hours you need a premium character. Actually you need 2-3 premium characters in order to use all the options. The mart and the factory are huge and ugly in my opinion. The mart of course gives Agnes a 16hour job aka 750$ But it doesn't worth it.. The studio... It's good but difficult to position. The community center it's fun to have around but let me remind you that

The lab comes with the professor who more often than not works for events currency... And simply because the building is wicked!

My advice is to always go for a character with a buidling for the cheapest price. Otto is the cheapest one.
Krusty Studios, Frink and the Community center I beleive are all the same price of 150. I would go:
1) Frink
2) Community
3) Krusty Studios

Okay, looks like Frink's lab is the winner for character tasks/season updates and earnings. I've been able to wait this long to have enough donuts though, I think I can wait until the Christmas update to see what premium items are added then.
