Zif socket recommendations

I am looking at 3 different styles of Zif sockets made by Aries in the
Mouser Electronics catalog:

http://www.mouser.com/catalog/621/938.pdf

The three styles are the Universal, the low pro and the the IC socket.
Other than the obvious differences in these sockets, can anyone
recommend which one would be most suitable for holding a 40 pin
Microchip PIC?

I don't have access to a good electronics shop in my area where I can
put my hands on these, so I am unsure what pitfalls to avoid. I am an
absolute beginner at electronics, so any insights would be appreciated.

Thanks,

B.C.

Why do you want to put it in a ZIF socket? Why not used ISP/ICD and
put it in a cheap socket?

I am building a programmer for the PIC, but I agree an ICSP setup may
be the way to go eventually.

The 'universal' type allows you to plug in a 300-mil wide IC package
such as the PIC 28-pin DIP package. This is useful for such things a
programmers that would accept a variety of chips. It's also got a nice
easy-to-operate handle. I think the others are more for occassional
use than for heavy use (eg. in a programmer).

Yes, I wonder if the non-universal sockets would wear out over time.
Without being able to actually use one before I buy, it is difficult to
judge their mechanical reliance.

But they will all hold a DIP-40 (600mil) package and make contact to
the pins, the question you need to answer is *why*.

The answer is a programmer, and for prototyping. Thanks for your response.

In which case, the Textool style is the standard. BTW, if you're
retrofitting, note that the pins typically require unusually large
holes for a socket.

That is the impression I get from looking at a lot of the DIY programmers
around the web. But for the cost of one 3M Textool, I could get three
Aries Lo-Pro styles. Plus, the Lo Pro has test points for all the pins,
which
may be useful. But, I am so new at the field that I don't really know what
is a pro or a con with most components.

BTW, if you're retrofitting, note that the pins typically require
unusually large
holes for a socket.

Good point, as I was wondering how easy it would be to use these sockets in
a breadboard, or use one Zif for several projects by setting it in another
standard socket.

Thanks,

I've found that the ZIF in a breadboard is iffy. the pins on a ZIF aren;t
that long. it's easy to rock the ZIF left and right. The ZIF takes up a
lot of breadboard space and what you have is 1 column of holes on
left and right of the ZIF. You have get a DIP socket , stick that on the
ZIF socket and then into the breadboard. Now the ZIF will make
contact and stay in the breadboard.

Here are a couple more to consider:
