Re: Milikan: recommendations needed

I have not used either, but Pasco equipment is always top quality in design and function. The founder of Pasco's first product was the Milikan apparatus and I have heard that it works well. I have also had nothing but excellent service and support from Pasco. Has anyone dealt with Tel-atomic?
Whether or not it is a real exposure concern, the minute I mention 'latex spheres' someone (student or administrator) will take issue with allergies. 

I vote for the Pasco model.

Hi -- I hope that everybody is enjoying nice summer time.

I have two quotes for the Milikan apparatus, from TEL-Atomic:  
(we have their cloud chamber)

and PASCO:

Tel-Atomic uses latex spheres and has everything in one piece, while PASCO is traditional oil and consists of many pieces. Tel-atomic is 35% more expensive, but this should not be a deciding factor.
Could you please have a look at the links and make your recommendations which one would be best suited for our needs. I have already purchased a video-flex camera which will allow projecting from the microscope on a computer monitor and/or overhead projector.
We will have a great new demo -- so please help me in this choice.
